Expand description

The EVM instance.

Defines the base struct of the VM implementation.

Fields

abi_version: i32

EVMC ABI version implemented by the VM instance.

Can be used to detect ABI incompatibilities. The EVMC ABI version represented by this file is in ::EVMC_ABI_VERSION.

name: *const i8

The name of the EVMC VM implementation.

It MUST be a NULL-terminated not empty string. The content MUST be UTF-8 encoded (this implies ASCII encoding is also allowed).

version: *const i8

The version of the EVMC VM implementation, e.g. “1.2.3b4”.

It MUST be a NULL-terminated not empty string. The content MUST be UTF-8 encoded (this implies ASCII encoding is also allowed).

destroy: Option<unsafe extern "C" fn(*mut evmc_instance)>

Pointer to function destroying the EVM instance.

This is a mandatory method and MUST NOT be set to NULL.

execute: Option<unsafe extern "C" fn(*mut evmc_instance, *mut evmc_context, evmc_revision, *const evmc_message, *const u8, usize) -> evmc_result>

Pointer to function executing a code by the EVM instance.

This is a mandatory method and MUST NOT be set to NULL.

get_capabilities: Option<unsafe extern "C" fn(*mut evmc_instance) -> u32>

A method returning capabilities supported by the VM instance.

The value returned MAY change when different options are set via the set_option() method.

A Client SHOULD only rely on the value returned if it has queried it after it has called the set_option().

This is a mandatory method and MUST NOT be set to NULL.

set_tracer: Option<unsafe extern "C" fn(*mut evmc_instance, Option<unsafe extern "C" fn(*mut evmc_tracer_context, usize, evmc_status_code, i64, usize, *const evmc_bytes32, usize, usize, usize, *const u8)>, *mut evmc_tracer_context)>

Optional pointer to function setting the EVM instruction tracer.

If the EVM does not support this feature the pointer can be NULL.

@deprecated Since EVMC 6.3, the tracing API has been deprecated as there have been some design flaws discovered. New API is expected to be introduced in future.

set_option: Option<unsafe extern "C" fn(*mut evmc_instance, *const i8, *const i8) -> evmc_set_option_result>

Optional pointer to function modifying VM’s options.

If the VM does not support this feature the pointer can be NULL.
