pub trait Decoder: Send + Sync {
// Required method
fn decode(
&self,
token_ids: &[TokenIdType],
skip_special_tokens: bool,
) -> Result<DecodeResult>;
}Expand description
Implementations must ensure that partial multi-byte sequences produce U+FFFD
(\u{FFFD}) in the output rather than returning Err. This is commonly achieved
via String::from_utf8_lossy (tiktoken) or library-internal byte-fallback handling
(HuggingFace). DecodeStream::step() relies on DecodeResult::Partial to detect
incomplete sequences and buffer tokens until the full character arrives.
Required Methods§
fn decode( &self, token_ids: &[TokenIdType], skip_special_tokens: bool, ) -> Result<DecodeResult>
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
