Struct SourceFile

pub struct SourceFile { /* private fields */ }

A SourceFile represents a single file stored in a super::SourceManager

Implementations

impl SourceFile

pub fn new( id: SourceId, path: impl Into<Arc<str>>, content: impl Into<Box<str>>, ) -> SourceFile

Create a new SourceFile from its raw components

pub const fn id(&self) -> SourceId

Get the SourceId associated with this file

pub fn name(&self) -> Arc<str>

Get the name of this source file

pub fn path(&self) -> &Path

Get the path of this source file as a std::path::Path

pub fn content(&self) -> &SourceContent

Returns a reference to the underlying SourceContent

pub fn line_count(&self) -> usize

Returns the number of lines in this file

pub fn len(&self) -> usize

Returns the number of bytes in this file

pub fn is_empty(&self) -> bool

Returns true if this file is empty

pub fn as_str(&self) -> &str

Get the underlying content of this file

pub fn as_bytes(&self) -> &[u8]

Get the underlying content of this file as a byte slice

pub fn source_span(&self) -> SourceSpan

Returns a SourceSpan covering the entirety of this file

pub fn source_slice(&self, span: impl Into<Range<usize>>) -> Option<&str>

Returns a subset of the underlying content as a string slice.

The bounds of the given span are character indices, not byte indices.

Returns None if the given span is out of bounds

pub fn slice( self: &Arc<SourceFile>, span: impl Into<Range<u32>>, ) -> SourceFileRef

Returns a SourceFileRef corresponding to the bytes contained in the specified span.

pub fn line_column_to_span(&self, line: u32, column: u32) -> Option<SourceSpan>

Get a SourceSpan which points to the first byte of the character at column on line

Returns None if the given line/column is out of bounds for this file.

pub fn location(&self, span: SourceSpan) -> FileLineCol

Get a FileLineCol equivalent to the start of the given SourceSpan

Trait Implementations

impl AsRef<[u8]> for SourceFile

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<Path> for SourceFile

fn as_ref(&self) -> &Path

Converts this type into a shared reference of the (usually inferred) input type.

impl AsRef<str> for SourceFile

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for SourceFile

fn clone(&self) -> SourceFile

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourceFile

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

Formats the value using the given formatter.

impl Hash for SourceFile

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 SourceFile

fn cmp(&self, other: &SourceFile) -> 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,

Restrict a value to a certain interval.

impl PartialEq for SourceFile

fn eq(&self, other: &SourceFile) -> 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.

impl PartialOrd for SourceFile

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl SourceCode for SourceFile

fn read_span<'a>( &'a self, span: &SourceSpan, context_lines_before: usize, context_lines_after: usize, ) -> Result<Box<dyn SpanContents<'a> + 'a>, MietteError>

Read the bytes for a specific span from this SourceCode, keeping a certain number of lines before and after the span as context.

impl Eq for SourceFile
