Struct apollo_compiler::NodeLocation

pub struct NodeLocation { /* private fields */ }

The source location of a parsed node: file ID and range within that file.

Implementations

impl NodeLocation

pub fn file_id(&self) -> FileId

Returns the file ID for this location

pub fn offset(&self) -> usize

Returns the offset from the start of the file to the start of the range, in UTF-8 bytes

pub fn end_offset(&self) -> usize

Returns the offset from the start of the file to the end of the range, in UTF-8 bytes

pub fn node_len(&self) -> usize

Returns the length of the range, in UTF-8 bytes

pub fn recompose(start_of: Option<Self>, end_of: Option<Self>) -> Option<Self>

Best effort at making a location with the given start and end

Trait Implementations

impl Clone for NodeLocation

fn clone(&self) -> NodeLocation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NodeLocation

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

Formats the value using the given formatter.

impl Hash for NodeLocation

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

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 PartialEq for NodeLocation

fn eq(&self, other: &NodeLocation) -> 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 Span for NodeLocation

type SourceId = FileId

The identifier used to uniquely refer to a source. In most cases, this is the fully-qualified path of the file.

fn source(&self) -> &FileId

Get the identifier of the source that this span refers to.

fn start(&self) -> usize

Get the start offset of this span.

fn end(&self) -> usize

Get the (exclusive) end offset of this span.

fn len(&self) -> usize

Get the length of this span (difference between the start of the span and the end of the span).

fn contains(&self, offset: usize) -> bool

Determine whether the span contains the given offset.
