LanguageVersion

Module std.compiler

import std.compiler;

Public declaration contracts and authored examples. A page can document several related symbols. Implementation bodies are excluded.

LanguageVersion

pub struct LanguageVersion

Carries the source-language semantic version as three unsigned fields.

The value is deterministic compiler input and is independent of compiler build identity, optimization profile, host state, and wall-clock time.

Example

module example.compiler_facts;
from std.compiler import CurrentLanguageEdition, CurrentLanguageVersion,
    CurrentTargetAbi, CurrentTargetArchitecture, CurrentTargetEndianness,
    CurrentTargetEnvironment, CurrentTargetObjectFormat,
    CurrentTargetOperatingSystem, PointerBitWidth, PointerByteAlignment,
    StackByteAlignment;
fn Main() -> i32 {
    if CurrentLanguageVersion.Major != 1 ||
        CurrentLanguageVersion.Minor != 0 ||
        CurrentLanguageVersion.Patch != 0 ||
        CurrentLanguageEdition != .V1 ||
        CurrentTargetArchitecture != .X86_64 ||
        CurrentTargetOperatingSystem != .Linux ||
        CurrentTargetEnvironment != .Gnu ||
        CurrentTargetObjectFormat != .Elf ||
        CurrentTargetEndianness != .Little ||
        CurrentTargetAbi != .SysVAMD64 || PointerBitWidth != 64 ||
        PointerByteAlignment != 8 || StackByteAlignment != 16 {
        return 1;
    }
    return 0;
}

LanguageVersion.Major

pub Major: u32;

Stores the compatibility-breaking language generation.

LanguageVersion.Minor

pub Minor: u32;

Stores the backward-compatible feature generation.

LanguageVersion.Patch

pub Patch: u32;

Stores the backward-compatible correction generation.

CurrentLanguageVersion

pub const CurrentLanguageVersion: LanguageVersion;

Exposes the exact language semantic version selected for this compilation. Return: The deterministic three-component version, initially 1.0.0.
