pub struct VersionConstraint {
pub ranges: Vec<PHPVersionRange>,
}Expand description
Tracks the PHP version intervals in which a symbol is available, derived
from Mago\AvailableSince / Mago\AvailableUntil attributes during
scanning.
Both attributes are repeatable, so a symbol can declare disjoint availability ranges (for example “available 8.1–8.3, removed in 8.4, brought back in 8.5”). An empty range list means “always available”; otherwise a version is allowed when some range contains it.
Fields§
§ranges: Vec<PHPVersionRange>Disjoint availability intervals in source order. Empty = unconstrained.
Implementations§
Source§impl VersionConstraint
impl VersionConstraint
pub const fn unconstrained() -> Self
pub const fn is_unconstrained(&self) -> bool
Sourcepub fn push_since(&mut self, version: PHPVersion)
pub fn push_since(&mut self, version: PHPVersion)
Records a new Mago\AvailableSince(version) claim — opens a fresh
range that stays open on the right until a matching AvailableUntil
claim closes it.
Sourcepub fn push_until(&mut self, version: PHPVersion)
pub fn push_until(&mut self, version: PHPVersion)
Records a new Mago\AvailableUntil(version) claim. Closes the most
recent open range if there is one; otherwise opens a brand-new range
with no min bound.
Sourcepub fn merge(&mut self, other: VersionConstraint)
pub fn merge(&mut self, other: VersionConstraint)
Folds other into self by unioning their availability ranges.
Sourcepub fn allows_version(&self, version: PHPVersion) -> bool
pub fn allows_version(&self, version: PHPVersion) -> bool
Returns true when version is allowed by any range in this
constraint.
Sourcepub fn allows_version_range(&self, range: PHPVersionRange) -> bool
pub fn allows_version_range(&self, range: PHPVersionRange) -> bool
Returns true when every PHP version in range is covered by the
union of ranges in this constraint. An open min/max on range is
treated as the platform’s known low/high bound.

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>

Returns a styled value derived from self with the background set to

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};

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().

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().

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);
