Struct HookMatcher 

pub struct HookMatcher {
    pub phases: Vec<HookPhase>,
    pub tool_name: Option<String>,
    pub cwd_prefix: Option<String>,
}

Pure filter that gates a hook on phase, tool name, and/or cwd prefix. phases empty = all phases match. tool_name / cwd_prefix None = no constraint. Allocation: O(phases count + name/prefix length) at construction.

Fields

phases: Vec<HookPhase>

Phases this hook applies to. Empty = all phases.

tool_name: Option<String>

Exact tool name filter (for PreToolUse). None = any tool.

cwd_prefix: Option<String>

Working-directory prefix filter. None = any cwd.

Implementations

impl HookMatcher

pub fn phases(phases: impl Into<Vec<HookPhase>>) -> Self

Match only specific phases. Allocation: one Vec. Complexity: O(phases count).

pub fn with_tool_name(self, name: impl Into<String>) -> Self

Add exact tool_name constraint (meaningful for PreToolUse). Allocation: one String. Complexity: O(name length).

pub fn with_cwd_prefix(self, prefix: impl Into<String>) -> Self

Add cwd_prefix constraint. Uses str::starts_with matching. Allocation: one String. Complexity: O(prefix length).

pub fn matches(&self, ctx: &HookContext) -> bool

True when ctx satisfies all non-empty constraints. cwd_prefix matches cwd == prefix or cwd starts with prefix + "/". This avoids treating /project as a prefix of /project2. Pure function; no heap allocation. Complexity: O(phases count + prefix length).

Trait Implementations

impl Clone for HookMatcher

fn clone(&self) -> HookMatcher

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HookMatcher

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

Formats the value using the given formatter.

impl Default for HookMatcher

fn default() -> HookMatcher

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HookMatcher

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for HookMatcher

fn eq(&self, other: &HookMatcher) -> 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.

impl Serialize for HookMatcher

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
