Struct TextReadRefusal 

pub struct TextReadRefusal {
    pub cause: TextReadCause,
    pub at: u64,
}

One refused text read: the established cause, and the byte it sits at.

Fields

cause: TextReadCause

The established cause.

at: u64

The byte position the cause was established at.

Implementations

impl TextReadRefusal

pub const fn coordinate(self) -> SourceCoordinate

Where this refusal sits, as a typed coordinate in the byte role.

The text route reads bytes, so every cause it establishes has a byte position and is born carrying it. Stating it in the shape SpanTable::coordinate_of answers in lets a caller report a read that never produced a capture — and therefore never produced a span table or a handle to look up in one.

Nonclaims

No table is consulted, because at this point there is none: the position is the refusal’s own, and the role says which text it counts into.

impl TextReadRefusal

pub fn diagnostic(&self, door: &Door) -> Diagnostic

Project this refused text read at the byte coordinate it established.

No caller supplies a coordinate or a phase on this road, so a pre-capture diagnostic cannot be paired with a different byte, semantic-origin coordinate, or refusal vocabulary.
