Struct miden_core::debuginfo::SourceContent

pub struct SourceContent { /* private fields */ }

Represents key information about a source file and its content:

• The path to the file (or its name, in the case of virtual files)
• The content of the file
• The byte offsets of every line in the file, for use in looking up line/column information

Implementations

impl SourceContent

pub fn new(path: Arc<str>, content: Box<str>) -> Self

Create a new SourceContent from the (possibly virtual) file path, and its content as a UTF-8 string.

When created, the line starts for this file will be computed, which requires scanning the file content once.

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

Get the name of this source file

pub fn path(&self) -> &Path

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

pub fn as_str(&self) -> &str

Returns the underlying content as a string slice

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

Returns the underlying content as a byte slice

pub fn len(&self) -> usize

Returns the size in bytes of the underlying content

pub fn is_empty(&self) -> bool

Returns true if the underlying content is empty

pub fn source_range(&self) -> Range<ByteIndex>

Returns the range of valid byte indices for 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 line_start(&self, line_index: LineIndex) -> Option<ByteIndex>

Returns the byte index at which the line corresponding to line_index starts

Returns None if the given index is out of bounds

pub fn last_line_index(&self) -> LineIndex

Returns the index of the last line in this file

pub fn line_range(&self, line_index: LineIndex) -> Option<Range<ByteIndex>>

Get the range of byte indices covered by the given line

pub fn line_index(&self, byte_index: ByteIndex) -> LineIndex

Get the index of the line to which byte_index belongs

pub fn line_column_to_offset( &self, line_index: LineIndex, column_index: ColumnIndex, ) -> Option<ByteIndex>

Get the ByteIndex corresponding to the given line and column indices.

Returns None if the line or column indices are out of bounds.

pub fn location(&self, byte_index: ByteIndex) -> Option<FileLineCol>

Get a FileLineCol corresponding to the line/column in this file at which byte_index occurs

Trait Implementations

impl Clone for SourceContent

fn clone(&self) -> SourceContent

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SourceContent

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

Formats the value using the given formatter.

impl Hash for SourceContent

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 Ord for SourceContent

fn cmp(&self, other: &Self) -> 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 SourceContent

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.

impl PartialOrd for SourceContent

fn partial_cmp(&self, other: &Self) -> 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.
