pub struct Files { /* private fields */ }
Expand description
A cheaply-clonable, persistent, codespan
-compatible collection of files.
Files
knows about the nickel standard library, and automatically loads it on creation
(but it doesn’t do parsing, or anything particularly expensive).
Cloning a Files
is cheap, and the underlying file data will be shared between clones
until one of them wants to modify a file. In that case, only the modified file(s) will
be duplicated.
Implementations§
Source§impl Files
impl Files
Sourcepub fn is_stdlib(&self, id: FileId) -> bool
pub fn is_stdlib(&self, id: FileId) -> bool
Does this file id point to a standard library file?
Sourcepub fn stdlib_modules(&self) -> impl Iterator<Item = (StdlibModule, FileId)>
pub fn stdlib_modules(&self) -> impl Iterator<Item = (StdlibModule, FileId)>
Returns the list of all standard library modules and their file ids.
Sourcepub fn add(
&mut self,
name: impl Into<OsString>,
source: impl Into<Rc<str>>,
) -> FileId
pub fn add( &mut self, name: impl Into<OsString>, source: impl Into<Rc<str>>, ) -> FileId
Adds a file to this collection, creating and returning a new file id.
The name does not need to be unique, and this method does not affect any other files with the same name.
Sourcepub fn update(&mut self, file_id: FileId, source: impl Into<Rc<str>>)
pub fn update(&mut self, file_id: FileId, source: impl Into<Rc<str>>)
Updates a source file in place.
Panics if file_id
is invalid.
Sourcepub fn source_span(&self, file_id: FileId) -> RawSpan
pub fn source_span(&self, file_id: FileId) -> RawSpan
Returns a span containing all of a source.
Panics if file_id
is invalid.
Sourcepub fn name(&self, id: FileId) -> &OsStr
pub fn name(&self, id: FileId) -> &OsStr
Returns the source’s name.
Panics if file_id
is invalid.
Sourcepub fn source_slice(&self, span: RawSpan) -> &str
pub fn source_slice(&self, span: RawSpan) -> &str
Returns a slice of the source’s contents.

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()

, which have the same functionality but

, which have the same functionality
but are pithier.

, which have the same functionality but are

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);
