pub struct StrMatcherBuilder { /* private fields */ }Available on crate feature
strmatch only.Expand description
Builder for StrMatcher. Carries minimum-tier policy and the
case-insensitivity flag.
Implementations§
Source§impl StrMatcherBuilder
impl StrMatcherBuilder
Sourcepub fn new() -> Self
pub fn new() -> Self
Create a builder with default options (no minimum tier, no case-insensitivity).
Sourcepub fn min_tier(self, tier: MatcherTier) -> Self
pub fn min_tier(self, tier: MatcherTier) -> Self
Reject (or warn about) patterns that classify below this tier.
Tier ordering (highest → lowest): Shape > Literal > Meta.
Setting min_tier(Literal) allows Shape and Literal but
triggers on_below_min for Meta.
Sourcepub fn on_below_min(self, policy: OnBelowMin) -> Self
pub fn on_below_min(self, policy: OnBelowMin) -> Self
What to do when a pattern falls below min_tier.
Sourcepub fn ascii_case_insensitive(self, enabled: bool) -> Self
pub fn ascii_case_insensitive(self, enabled: bool) -> Self
Build a case-insensitive matcher.
The pattern is wrapped in (?i:...) before parsing. Both the
literal and shape tiers honour the flag via
aho_corasick::AhoCorasickBuilder::ascii_case_insensitive;
shape-tier dispatch downgrades to the literal tier when this
flag is set, since memchr does not fold case.
Sourcepub fn build(&self, pattern: &str) -> Result<StrMatcher, BuildError>
pub fn build(&self, pattern: &str) -> Result<StrMatcher, BuildError>
Build the matcher.
§Errors
Returns Err if the pattern fails to parse or violates the
min_tier policy with on_below_min = Reject.
Source§impl StrMatcherBuilder
impl StrMatcherBuilder
Sourcepub fn build_set<I, S>(&self, patterns: I) -> Result<StrMatcherSet, BuildError>
pub fn build_set<I, S>(&self, patterns: I) -> Result<StrMatcherSet, BuildError>
Build a StrMatcherSet from an iterator of patterns.
min_tier + on_below_min apply per pattern. First failure
short-circuits the build. Unanchored literals fold into a
merged AC; anchored / regex patterns stay individual.

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};

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

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};

Enables the yansi Quirk value.
This method should be used rarely. Instead, prefer to use quirk-specific

wrap(), which have the same functionality but are
pithier.
§Example
Enable wrapping using .quirk():
use yansi::{Paint, Quirk};

👎Deprecated since 1.0.1: renamed to resetting() due to conflicts with Vec::clear().

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);
