The EVM instance.

Defines the base struct of the VM implementation.

Fields

abi_version: c_int

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 c_char

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 c_char

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: evmc_destroy_fn

Pointer to function destroying the EVM instance.

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

execute: evmc_execute_fn

Pointer to function executing a code by the EVM instance.

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

get_capabilities: evmc_get_capabilities_fn

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: evmc_set_tracer_fn

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: evmc_set_option_fn

Optional pointer to function modifying VM’s options.

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