Detailed Description

Dynamic config schema for map-like options.

The schema supports:

• Option declaration (def_option<T>)
• Optional canonicalizer (set_canonicalizer)
• Resolution (Resolve) that performs validation/defaulting, unknown-key policy, and canonicalization (last).

Member Typedef Documentation

Canonicalizer

using tvm::ir::ConfigSchema::Canonicalizer = ffi::TypedFunction<ConfigMap(ConfigMap)>

ConfigMap

using tvm::ir::ConfigSchema::ConfigMap = ffi::Map<ffi::String, ffi::Any>

Member Function Documentation

def_option()

template<typename T , typename... Traits>

ConfigSchema & tvm::ir::ConfigSchema::def_option ( const ffi::String &  key, Traits &&...  traits  )

inline

Declare a typed option.

Validation/coercion is implicitly generated from T. Additional optional traits may be supplied (e.g. refl::DefaultValue, const char* doc).

Template Parameters

T	The canonical value type of this option.
Traits	Optional metadata/traits.

Parameters

key	Option key.
traits	Optional traits.

Returns

Reference to *this for chaining.

HasOption()

bool tvm::ir::ConfigSchema::HasOption ( const ffi::String &  key ) const

inline

Check if an option with the given key exists.

ListOptions()

const std::vector< OptionEntry > & tvm::ir::ConfigSchema::ListOptions ( ) const

inline

List declared options in declaration order.

Returns

Const reference to the option entries vector.

Resolve()

ConfigMap tvm::ir::ConfigSchema::Resolve ( ConfigMap  config ) const

inline

Default/validate, then canonicalize a config object.

Resolve flow: 1) Validate/coerce declared options in declaration order. 2) Materialize defaults and enforce required options. 3) Apply unknown-key policy. 4) Run canonicalizer as final step.

Parameters

config

Input config object.

Returns

Canonical validated config object.

Exceptions

ValueError/TypeError

with option context.

set_canonicalizer()

void tvm::ir::ConfigSchema::set_canonicalizer ( Canonicalizer  f )

inline

Set whole-object canonicalizer.

set_error_on_unknown()

void tvm::ir::ConfigSchema::set_error_on_unknown ( bool  value )

inline

Set whether unknown keys trigger an error.
