Struct Representation 

#[non_exhaustive]
pub struct Representation {
    pub body: Bytes,
    pub content_type: String,
    pub headers: Vec<(String, String)>,
}

Stored representation passed to write operations.

Header persistence policy belongs to adapters. The engine treats these pairs as opaque metadata.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

body: Bytes

Opaque payload bytes stored verbatim.

content_type: String

MIME type recorded with the body.

headers: Vec<(String, String)>

Arbitrary metadata header pairs. Header-name de-duplication and allow/deny policy belong to the adapter that constructs this struct.

Browser-facing adapters apply their own filtering because clients may execute metadata as policy. Other adapters may pass headers through as opaque key-value metadata.

Implementations

impl Representation

pub fn new( body: impl Into<Bytes>, content_type: impl Into<String>, headers: Vec<(String, String)>, ) -> Self

Builds a stored representation from payload bytes, content type, and adapter-supplied metadata headers.
