pub struct Located<E> {
    inner: E,
    pos: TextRange,
    current_file: Option<FileId>,
    path: Option<PathBuf>,
    file_override: FileOverride,

}

Wraps an object with location data

Fields

inner: E

Inner error, without location information

pos: TextRange

Position at which the error occurred

current_file: Option<FileId>

File identifier for the error

path: Option<PathBuf>

Path corresponding to the file identifier

file_override: FileOverride

Overriden file location

line_number: u32

Resolved line number

column: u32

Resolved column number

Implementations

impl<E> Located<E>

pub fn builder() -> LocatedBuilder

Create a builder for this located type

pub fn map<F>(self, f: impl FnOnce(E) -> F) -> Located<F>

Transform the inner value wrapped by this instance

Parameters

• f: function to apply to the inner value

pub fn inner(&self) -> &E

Return a reference to the inner value

pub fn into_inner(self) -> E

Return the inner value

pub fn current_file(&self) -> Option<FileId>

Get the current file identifier

pub fn set_current_file(&mut self, current_file: FileId)

Set the current file identifier

pub fn pos(&self) -> TextRange

Get the raw position into the source

pub fn line(&self) -> u32

Get the line number for this location

pub fn col(&self) -> u32

Get the column number for this location

Trait Implementations

impl<E: Clone> Clone for Located<E>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<E: Debug> Debug for Located<E>

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

Formats the value using the given formatter.

impl<E: Display> Display for Located<E>

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

Formats the value using the given formatter.

impl<E: Error> Error for Located<E>

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl<E: PartialEq> PartialEq for Located<E>

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

Tests for self and other values to be equal, and is used by ==.

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

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