pub struct FormatRegistry { /* private fields */ }Expand description
A registry of config file formats.
This allows registering multiple formats and selecting the appropriate one based on file extension.
Implementations§
Source§impl FormatRegistry
impl FormatRegistry
Sourcepub fn with_defaults() -> Self
pub fn with_defaults() -> Self
Create a registry with the default JSON format.
Sourcepub fn register<F: ConfigFormat + 'static>(&mut self, format: F)
pub fn register<F: ConfigFormat + 'static>(&mut self, format: F)
Register a new format.
Sourcepub fn find_by_extension(&self, extension: &str) -> Option<&dyn ConfigFormat>
pub fn find_by_extension(&self, extension: &str) -> Option<&dyn ConfigFormat>
Find a format that handles the given file extension.
The extension should not include the leading dot.
Sourcepub fn parse(
&self,
contents: &str,
extension: &str,
) -> Result<ConfigValue, ConfigFormatError>
pub fn parse( &self, contents: &str, extension: &str, ) -> Result<ConfigValue, ConfigFormatError>
Parse a config file, automatically selecting the format based on extension.
Sourcepub fn parse_file(
&self,
path: &Utf8Path,
contents: &str,
) -> Result<ConfigValue, ConfigFormatError>
pub fn parse_file( &self, path: &Utf8Path, contents: &str, ) -> Result<ConfigValue, ConfigFormatError>
Parse a config file and set provenance on all values.
This is the preferred method for loading config files, as it ensures all values have proper provenance tracking for error messages.
Sourcepub fn extensions(&self) -> Vec<&str>
pub fn extensions(&self) -> Vec<&str>
Get all registered extensions.

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().

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():

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().

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>
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);
