Struct ExecutionEnv 

pub struct ExecutionEnv { /* private fields */ }

Represents the environment accessible in the contract execution context.

ExecutionEnv provides pre- and post-execution methods for the contract, such as performing non-reentrant checks and handling the attached value.

Implementations

impl ExecutionEnv

pub fn new(env: Rc<ContractEnv>) -> Self

Creates a new ExecutionEnv instance.

pub fn non_reentrant_before(&self)

Performs non-reentrant checks before executing a function.

pub fn non_reentrant_after(&self)

Resets the reentrancy guard after executing a function.

pub fn handle_attached_value(&self)

Handles the attached value in the execution environment.

pub fn clear_attached_value(&self)

Clears the attached value in the execution environment.

pub fn get_named_arg<T: FromBytes + EntrypointArgument>(&self, name: &str) -> T

Retrieves the value of a named argument from the execution environment.

Returns

The deserialized value of the named argument. If the argument does not exist or deserialization fails, the contract will revert.

pub fn migrate_schemas(&self, new_schemas: BTreeMap<String, Schema>)

Migrates the schemas in the contract storage to the new schemas.
