Struct DecoderContext 

pub struct DecoderContext {
    pub adapter_path: Option<String>,
    pub vm_traces: Option<bool>,
    pub block_position: BlockPositionAssumption,
    pub chain: Option<Chain>,
    /* private fields */
}

Context struct containing attributes for decoders

This struct can be extended to include additional attributes for other decoders in the future

Fields

adapter_path: Option<String>

vm_traces: Option<bool>

block_position: BlockPositionAssumption

What quotes may assume about the swap’s position within its execution block.

Only consumed by protocols that price the first swap of a block differently (currently aerodrome_slipstreams). Once the pool has been touched in the execution block, position is a known fact and the assumption has no effect.

chain: Option<Chain>

Chain the decoded components live on.

Stamped by TychoStreamDecoder at registration, so it is None only for a context that never went through a decoder. Decoders whose behaviour depends on the chain (currently the Uniswap V4 hook handler registry) reject the snapshot when it is None rather than assume one.

Implementations

impl DecoderContext

pub fn new() -> Self

pub fn chain(self, chain: Chain) -> Self

Declares the chain the decoded components live on.

Registering the context with a TychoStreamDecoder overrides whatever is set here with the decoder’s own chain.

pub fn block_position_assumption( self, assumption: BlockPositionAssumption, ) -> Self

pub fn vm_adapter_path<S: Into<String>>(self, path: S) -> Self

pub fn vm_traces(self, trace: bool) -> Self

Trait Implementations

impl Clone for DecoderContext

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DecoderContext

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DecoderContext

fn default() -> Self

Returns the “default value” for a type.
