Struct MapEncoder 

pub struct MapEncoder<'a> { /* private fields */ }

Available on crate feature alloc only.

Builder for writing map entries into a canonical CBOR stream.

Implementations

impl MapEncoder<'_>

pub fn entry<F>(&mut self, key: &str, f: F) -> Result<(), CborError>

where F: FnOnce(&mut Encoder) -> Result<(), CborError>,

Insert a map entry. Keys must be in canonical order; duplicates are rejected.

Errors

Returns an error if encoding fails, if keys are out of order, or if duplicates are found.

pub fn entry_raw_key<F>( &mut self, key: EncodedTextKey<'_>, f: F, ) -> Result<(), CborError>

where F: FnOnce(&mut Encoder) -> Result<(), CborError>,

Insert a map entry using a pre-encoded canonical text key.

This avoids re-encoding keys when splicing from validated canonical bytes.

Errors

Returns an error if encoding fails, if keys are out of order, or if duplicates are found.
