Struct contract_transcode::env_types::EnvTypesTranscoder

pub struct EnvTypesTranscoder { /* private fields */ }

Provides custom encoding and decoding for predefined environment types.

Implementations

impl EnvTypesTranscoder

pub fn new( encoders: HashMap<u32, Box<dyn CustomTypeEncoder>>, decoders: HashMap<u32, Box<dyn CustomTypeDecoder>> ) -> Self

Construct an EnvTypesTranscoder from the given type registry.

pub fn try_encode<O>( &self, type_id: u32, value: &Value, output: &mut O ) -> Result<bool>where O: Output,

If the given type id is for a type with custom encoding, encodes the given value with the custom encoder and returns true. Otherwise returns false.

Errors

• If the custom encoding fails.

pub fn try_decode(&self, type_id: u32, input: &mut &[u8]) -> Result<Option<Value>>

If the given type lookup id is for an environment type with custom decoding, decodes the given input with the custom decoder and returns Some(value). Otherwise returns None.

Errors

• If the custom decoding fails.

impl Default for EnvTypesTranscoder

fn default() -> EnvTypesTranscoder

Returns the “default value” for a type.
