Struct EnvironmentPattern 

pub struct EnvironmentPattern { /* private fields */ }

A wildcard pattern matched against an environment variable name.

The pattern language is deliberately small and portable: * matches zero or more Unicode scalar values and ? matches one. Matching is case-insensitive so the same policy is safe on POSIX and Windows hosts.

Implementations

impl EnvironmentPattern

pub fn new(pattern: impl Into<String>) -> Result<Self, CommandError>

Creates a validated environment-variable pattern.

pub fn as_str(&self) -> &str

Returns the original pattern text.

Trait identity is based on the same case-insensitive canonical form as Self::matches, while this accessor preserves the caller’s spelling for diagnostics and serialization.

pub fn matches(&self, name: &str) -> bool

Returns whether this pattern matches an environment variable name.

Trait Implementations

impl Clone for EnvironmentPattern

fn clone(&self) -> EnvironmentPattern

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EnvironmentPattern

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for EnvironmentPattern

impl Hash for EnvironmentPattern

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for EnvironmentPattern

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for EnvironmentPattern

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl PartialOrd for EnvironmentPattern

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
