Struct contract_transcode::env_types::EnvTypesTranscoder
source · pub struct EnvTypesTranscoder { /* private fields */ }Expand description
Provides custom encoding and decoding for predefined environment types.
Implementations§
source§impl EnvTypesTranscoder
impl EnvTypesTranscoder
sourcepub fn new(
encoders: HashMap<u32, Box<dyn CustomTypeEncoder>>,
decoders: HashMap<u32, Box<dyn CustomTypeDecoder>>
) -> Self
pub fn new( encoders: HashMap<u32, Box<dyn CustomTypeEncoder>>, decoders: HashMap<u32, Box<dyn CustomTypeDecoder>> ) -> Self
Construct an EnvTypesTranscoder from the given type registry.
sourcepub fn try_encode<O>(
&self,
type_id: u32,
value: &Value,
output: &mut O
) -> Result<bool>where
O: Output,
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.
sourcepub fn try_decode(
&self,
type_id: u32,
input: &mut &[u8]
) -> Result<Option<Value>>
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.
