Struct TupleBuilder 

pub struct TupleBuilder { /* private fields */ }

The parts a caller supplies, with the rest derived.

A builder rather than ten arguments, because eight of the ten calls in this workspace supply three of them and a function with seven defaulted parameters is a function nobody calls correctly.

Implementations

impl TupleBuilder

pub const fn new(arch: Arch, os: Os) -> Self

Start from the two fields that have no default.

pub const fn sub_arch(self, sub_arch: SubArch) -> Self

Set the baseline within the architecture family.

pub const fn endian(self, endian: Endian) -> Self

Set the byte order, overriding the architecture’s default.

pub const fn data_model(self, data_model: DataModel) -> Self

Set the data model, overriding the one derived from the architecture and OS. The only target in the matrix that needs this is x86_64-linux-gnux32.

pub const fn os_version(self, version: Version) -> Self

Set the OS version, which is a deployment target on Darwin and a preview number on WASI.

pub const fn env(self, env: Env) -> Self

Set the environment, overriding the OS default.

pub const fn env_version(self, version: Version) -> Self

Set the environment version, which is a glibc version or an Android API level.

pub const fn abi(self, abi: Abi) -> Self

Set the float ABI.

pub fn build(self) -> Result<TargetTuple, Error>

Derive the remaining fields and check the combination describes a machine.

Errors

Returns the specific mismatch, never a generic failure. A caller that cannot say which component the user got wrong produces a diagnostic the user cannot act on.
