Struct FieldPredicate 

pub struct FieldPredicate {
    pub path: String,
    pub value: Value,
}

One field-level equality predicate within a task-events: check.

path is a dot-separated key into Event.fields (e.g. "error.code"). Evaluators prepend $. when translating to a JSONPath filter.

Fields

path: String

Dot-separated field path, e.g. "error.code", "file.path".

value: Value

Expected value — matched for equality. String, number, or bool.

Implementations

impl FieldPredicate

pub fn matches(&self, fields: &Value) -> bool

Returns true when this predicate matches the given event fields JSON object.

The path is traversed as dot-separated keys (e.g. "error.code" → fields["error"]["code"]). A missing key or a type mismatch returns false.

Trait Implementations

impl Clone for FieldPredicate

fn clone(&self) -> FieldPredicate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldPredicate

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FieldPredicate

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

where __D: Deserializer<'de>,

impl PartialEq for FieldPredicate

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