Detailed Description

ABI-stable tagged union representing a resource cost or budget.

This struct is a C-safe variant that can be passed by value across the plugin DLL boundary. The kind field selects which member of the value union is active. The value.reserved_words storage reserves space for future resource types without changing the struct layout.

Adding new resource types requires only: (a) a new OrtResourceCountKind enum value, (b) a new union member. No new C API functions are needed.

Since

Version 1.26.

Constructor & Destructor Documentation

OrtResourceCount()

OrtResourceCount::OrtResourceCount ( )

inlinenoexcept

Default-construct a None (unset) resource count.

Member Function Documentation

AsTotalBytes()

uint64_t OrtResourceCount::AsTotalBytes ( ) const

inlinenoexcept

Read the total_bytes value (caller must check kind first).

FromTotalBytes()

static OrtResourceCount OrtResourceCount::FromTotalBytes ( uint64_t  bytes )

inlinestaticnoexcept

Construct a resource count representing total bytes.

None()

static OrtResourceCount OrtResourceCount::None ( )

inlinestaticnoexcept

Construct a zero/unset resource count.

Member Data Documentation

kind

uint32_t OrtResourceCount::kind

OrtResourceCountKind discriminator.

reserved

uint32_t OrtResourceCount::reserved

Must be zero. Ensures natural alignment for the value union.

reserved_words

uint64_t OrtResourceCount::reserved_words[6]

48 bytes fixed storage for future resource types.

total_bytes

uint64_t OrtResourceCount::total_bytes

Active when kind == OrtResourceCountKind_TotalBytes.

[union]

union { ... } OrtResourceCount::value
