Struct SourceSpan

pub struct SourceSpan {
    pub start: u32,
    pub end: u32,
    pub file: SourceID,
}

A type representing a single line of a [Source].

Fields

start: u32

The start offset of the span

end: u32

The end offset of the span

file: SourceID

The file id of the span

Implementations

impl SourceSpan

pub fn new(file: SourceID, start: u32, end: u32) -> Self

Create a new source_text with the given start and end offsets, and the given file.

pub fn get_range(&self) -> Range<u32>

Create a new source_text with the given start and end offsets, and the given file.

pub fn get_start(&self) -> u32

Get the start offset of this source_text.

Offsets are zero-indexed character offsets from the beginning of the identifier.

pub fn get_end(&self) -> u32

Get the (exclusive) end offset of this source_text.

The end offset should always be greater than or equal to the start offset as given by [Span::start].

Offsets are zero-indexed character offsets from the beginning of the identifier.

pub fn set_range(&mut self, range: Range<u32>)

Create a new source_text with the given start and end offsets, and the given file.

pub fn with_range(self, range: Range<u32>) -> Self

Create a new source_text with the given start and end offsets, and the given file.

pub fn get_file(&self) -> SourceID

Create a new source_text with the given start and end offsets, and the given file.

pub fn set_file(&mut self, file: SourceID)

Create a new source_text with the given start and end offsets, and the given file.

pub fn with_file(self, file: SourceID) -> Self

Create a new source_text with the given start and end offsets, and the given file.

pub fn length(&self) -> u32

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

pub fn contains(&self, offset: u32) -> bool

Determine whether the source_text contains the given offset.

Trait Implementations

impl Clone for SourceSpan

fn clone(&self) -> SourceSpan

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SourceSpan

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

Formats the value using the given formatter.

impl Default for SourceSpan

fn default() -> SourceSpan

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SourceSpan

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SourceSpan

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

Formats the value using the given formatter.

impl Hash for SourceSpan

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 SourceSpan

fn eq(&self, other: &SourceSpan) -> 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 Serialize for SourceSpan

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
