Struct EntryPointsCaller 

pub struct EntryPointsCaller { /* private fields */ }

A struct representing an entry point caller.

The caller is used by the host environment to call entry points of a contract.

This struct is responsible for calling the entry points of a contract. It holds the host environment, a list of entry points, and a function pointer that takes a contract environment and a call definition as arguments and returns a result in the form of bytes.

Implementations

impl EntryPointsCaller

pub fn new( host_env: HostEnv, entry_points: Vec<EntryPoint>, f: fn(contract_env: ContractEnv, call_def: CallDef) -> OdraResult<Bytes>, ) -> Self

Creates a new instance of EntryPointsCaller.

Arguments

• host_env - The host environment.
• entry_points - A collection of available entry points.
• f - A function pointer that performs a call using a given contract environment and a call definition and returns a result in the form of bytes.

Returns

A new instance of EntryPointsCaller.

pub fn call(&self, call_def: CallDef) -> OdraResult<Bytes>

Calls the entry point with the given call definition. Returns the result of the entry point call in the form of bytes.

pub fn entry_points(&self) -> &[EntryPoint]

Returns a reference to the list of entry points.

pub fn remove_entry_point(&mut self, name: &str)

Removes an entry point by its name.
