pub struct SourceMap {
pub entries: Vec<SourceMapEntry>,
pub mappings: Vec<SourceMapping>,
pub generated_file: String,
pub sources: Vec<SourceInfo>,
}Expand description
Maps AIR source spans to generated code spans.
Populated by JS/TS code generators with pointwise mappings from generated
(line, col) back to source (line, col). For other targets, only the
legacy entries list (AIR node id → target byte range) is populated.
Fields§
§entries: Vec<SourceMapEntry>Legacy entries keyed by AIR node id (present for all targets).
mappings: Vec<SourceMapping>Pointwise position mappings from generated code to source.
generated_file: StringThe generated output file these mappings refer to (e.g. "output.js").
sources: Vec<SourceInfo>Source files referenced by mappings, in file-id order.
Each entry is (path, optional_inline_content).
Implementations§
Source§impl SourceMap
impl SourceMap
Sourcepub fn resolve_positions(&mut self, sources_content: &[&str])
pub fn resolve_positions(&mut self, sources_content: &[&str])
Fills in src_line and src_col on every mapping by looking up
src_offset inside sources_content, which is indexed by
src_file_id. Mappings whose src_file_id is out of range are left
unresolved.
Sourcepub fn to_source_map_v3_json(&self) -> String
pub fn to_source_map_v3_json(&self) -> String
Emits a Source Map v3 JSON document referring to this map’s
generated_file and sources. Only mappings whose src_line is
non-zero are included.

Source§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the foreground set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red() and
green(), which have the same functionality but are
pithier.
§Example
Set foreground color to white using fg():
use yansi::{Paint, Color};
painted.fg(Color::White);Set foreground color to white using white().
use yansi::Paint;
painted.white();Source§fn bright_black(&self) -> Painted<&T>

Source§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self with the background set to
value.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red() and
on_green(), which have the same functionality but
are pithier.
§Example
Set background color to red using fg():
use yansi::{Paint, Color};
painted.bg(Color::Red);Set background color to red using on_red().
use yansi::Paint;
painted.on_red();Source§fn on_primary(&self) -> Painted<&T>

Source§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling Attribute value.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold() and
underline(), which have the same functionality
but are pithier.
§Example
Make text bold using attr():
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);Make text bold using using bold().
use yansi::Paint;
painted.bold();Source§fn rapid_blink(&self) -> Painted<&T>

Source§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask() and
wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);Enable wrapping using wrap().
use yansi::Paint;
painted.wrap();Source§fn clear(&self) -> Painted<&T>
👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
fn clear(&self) -> Painted<&T>
renamed to resetting() due to conflicts with Vec::clear().
The clear() method will be removed in a future release.
Source§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the Condition value
applies. Replaces any previous condition.
See the crate level docs for more details.
§Example
Enable styling painted only when both stdout and stderr are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
