Struct CodePattern 

pub struct CodePattern {
    pub node: NodeKind,
    pub arm_count: Option<usize>,
    pub arms: Option<Vec<ArmPattern>>,
    pub children: HashMap<String, PatternExpr>,
    pub capture: Option<String>,
    pub ellipsis: bool,
}

AST Pattern for structural matching

Fields

node: NodeKind

AST node type to match

arm_count: Option<usize>

Required arm count (for Match nodes)

arms: Option<Vec<ArmPattern>>

Arm patterns (for Match nodes, order-independent matching)

children: HashMap<String, PatternExpr>

Child patterns (field name -> pattern)

capture: Option<String>

Capture variable (e.g., “$RECEIVER”)

ellipsis: bool

Match zero or more items (ellipsis)

Implementations

impl CodePattern

pub fn new(node: NodeKind) -> Self

Create a new CodePattern for the given node kind

pub fn with_child(self, name: impl Into<String>, pattern: PatternExpr) -> Self

Add a child pattern

pub fn with_capture(self, var: impl Into<String>) -> Self

Set capture variable

pub fn with_ellipsis(self) -> Self

Set ellipsis mode

Trait Implementations

impl Clone for CodePattern

fn clone(&self) -> CodePattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CodePattern

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CodePattern

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for CodePattern

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for CodePattern

fn eq(&self, other: &CodePattern) -> 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 CodePattern

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
