Struct glsl_lang::ast::NodeSpan

pub struct NodeSpan {
    source_id: FileId,
    range: TextRange,
}

Span information for a node, constructed from a pair of LexerPositions

Fields

source_id: FileId

range: TextRange

Implementations

impl NodeSpan

pub fn new(source_id: FileId, range: TextRange) -> NodeSpan

Create a new node span

pub fn from_lexer(start: LexerPosition, end: LexerPosition) -> NodeSpan

Create a new node span from two lexer positions

pub fn new_start(source_id: FileId) -> NodeSpan

Return a 0-length span located at the start of the given source

This may be used in span range queries.

pub fn new_end(source_id: FileId, length: usize) -> NodeSpan

Return a 0-length span located at the end of the given source (as indicated by the offset)

This may be used in span range queries.

pub fn source_id(&self) -> FileId

Return the source identifier for this node span

pub fn range(&self) -> TextRange

Return the span range

pub fn is_empty(&self) -> bool

Return true if this range is empty

pub fn len(&self) -> TextSize

Return the length of this span

pub fn start(&self) -> LexerPosition

Return the start of this span as a LexerPosition

pub fn end(&self) -> LexerPosition

Return the end of this span as a LexerPosition

Trait Implementations

impl Clone for NodeSpan

fn clone(&self) -> NodeSpan

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NodeSpan

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NodeSpan

fn deserialize<__D>( __deserializer: __D, ) -> Result<NodeSpan, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<NodeSpan> for FileId

fn from(value: NodeSpan) -> FileId

Converts to this type from the input type.

impl From<NodeSpan> for TextRange

fn from(value: NodeSpan) -> TextRange

Converts to this type from the input type.

impl Hash for NodeSpan

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for NodeSpan

fn cmp(&self, other: &NodeSpan) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for NodeSpan

fn eq(&self, other: &NodeSpan) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for NodeSpan

fn partial_cmp(&self, other: &NodeSpan) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for NodeSpan

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
