Span

ruff_db::diagnostic

Struct Span 

Source 
pub struct Span { /* private fields */ }
Expand description

A span represents the source of a diagnostic.

It consists of a File and an optional range into that file. When the range isn’t present, it semantically implies that the diagnostic refers to the entire file. For example, when the file should be executable but isn’t.

Implementations§

Source§

impl Span

Source

pub fn file(&self) -> &UnifiedFile

Returns the UnifiedFile attached to this Span.

Source

pub fn range(&self) -> Option<TextRange>

Returns the range, if available, attached to this Span.

When there is no range, it is convention to assume that this Span refers to the corresponding File as a whole. In some cases, consumers of this API may use the range 0..0 to represent this case.

Source

pub fn with_range(self, range: TextRange) -> Span

Returns a new Span with the given range attached to it.

Source

pub fn with_optional_range(self, range: Option<TextRange>) -> Span

Returns a new Span with the given optional range attached to it.

Source

pub fn expect_ty_file(&self) -> File

Returns the File attached to this Span.

Panics if the file is a UnifiedFile::Ruff instead of a UnifiedFile::Ty.

Source

pub fn as_ruff_file(&self) -> Option<&SourceFile>

Returns the SourceFile attached to this Span.
