Struct CommandPattern 

pub struct CommandPattern {
    pub tokens: Vec<String>,
    pub has_glob_suffix: bool,
}

A parsed allowlist pattern. Matches against an argv slice of any AsRef<str> type (e.g. &[String], &[&str], &[Cow<'_, str>]).

Fields

tokens: Vec<String>

has_glob_suffix: bool

Implementations

impl CommandPattern

pub fn parse(s: &str) -> Result<Self, String>

Parse a single pattern string. Tokens are whitespace-separated. A trailing :* (no whitespace before it) marks the pattern as a prefix match; otherwise the pattern is exact-length.

Errors:

• empty / whitespace-only input
• a lone :* with no preceding tokens

pub fn matches<S: AsRef<str>>(&self, argv: &[S]) -> bool

Match this pattern against an argv slice ([program, arg1, arg2, ...]).

Generic over S: AsRef<str> so callers can pass &[String] (existing) or &[&str] / &[Cow<'_, str>] (the canonical-ABI borrow path in host_commands_exec).

Trait Implementations

impl Clone for CommandPattern

fn clone(&self) -> CommandPattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CommandPattern

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

Formats the value using the given formatter.

impl PartialEq for CommandPattern

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
