Struct ErrorField 

pub struct ErrorField {
    pub key: Cow<'static, str>,
    pub value: Cow<'static, str>,
}

A key-value metadata field attached to a QqlError for structured context.

Use QqlError::with_field or the convenience builders (QqlError::with_collection, QqlError::with_status, etc.) to attach machine-readable context that clients can inspect without parsing the human-readable message string.

Fields

key: Cow<'static, str>

Field name, e.g. collection or status_code.

value: Cow<'static, str>

Field value as a string.

Implementations

impl ErrorField

pub fn new( key: impl Into<Cow<'static, str>>, value: impl Into<Cow<'static, str>>, ) -> Self
