Struct UnreadableSlice 

pub struct UnreadableSlice {
    pub encoding: Option<String>,
    pub error: String,
}

An introspect reply that arrived and could not be read as a registry slice (RFC 08 §6, v1.44; #491): what it declared, and the first line of why it did not read.

Three causes land here, and the shape does not tell them apart because the reader does not need it to — the error line does: a declared Encoding that is neither spelling (application/json), a document malformed in the spelling it declared (a TOML file declared application/kdl is read as KDL, never sniffed back), or one that parses but is not a slice.

Fields

encoding: Option<String>

The reply’s Encoding, verbatim — None when it declared none, which is itself the fact (the undeclared row of RFC 08 §6’s table reads as TOML), not an unasked question.

error: String

The parse error’s first line. A TOML error’s later lines are a caret diagram of the source, which a table row cannot carry and a script does not want.

Implementations

impl UnreadableSlice

pub fn new(encoding: Option<String>, error: &dyn Display) -> UnreadableSlice

From the reply’s declared encoding and whatever refused it — the first line of its Display, trimmed.

pub fn sentence(&self) -> String

The one sentence both explorers draw (#491): “introspect answered, slice unreadable (application/kdl: …)” — the house counterpart of “no introspect reply — capabilities unknown, not absent”, and like it a statement about the fetch, never about the producer’s capabilities.
