Struct SourceSpan 

pub struct SourceSpan {
    pub text: String,
    pub start: Option<SourceLocation>,
    pub end: Option<SourceLocation>,
    pub url: String,
    pub context: String,
}

A chunk of a source file.

Fields

text: String

The text covered by the source span. Compilers must guarantee that this is the text between start.offset and end.offset in the source file referred to by url.

start: Option<SourceLocation>

The location of the first character in this span. Mandatory.

end: Option<SourceLocation>

The location of the first character after this span. Optional.

If this is omitted, it indicates that the span is empty and points immediately before start. In that case, text must be empty.

This must not point to a location before start.

url: String

The URL of the file to which this span refers.

This may be empty, indicating that the span refers to a CompileRequest.StringInput file that doesn’t specify a URL.

context: String

Additional source text surrounding this span.

If this isn’t empty, it must contain text. Furthermore, text must begin at column start.column of a line in context.

This usually contains the full lines the span begins and ends on if the span itself doesn’t cover the full lines.

Trait Implementations

impl Clone for SourceSpan

fn clone(&self) -> SourceSpan

Returns a duplicate 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() -> Self

Returns the “default value” for a type.

impl Message for SourceSpan

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

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.
