Struct PrepareSpec 

pub struct PrepareSpec<'a> {
    pub data: DataSpec<'a>,
    pub libtorch: Option<&'a str>,
    pub active_libtorch: Option<&'a (PathBuf, String)>,
    pub source: Option<SourceSpec<'a>>,
    pub devices: Option<&'a [u8]>,
}

Everything this box has to settle before it dials.

Fields

data: DataSpec<'a>

libtorch: Option<&'a str>

libtorch variant to acquire: auto, cpu, cu126, cu128, rocm7.0, rocm7.1. None leaves this box on whatever it already has.

active_libtorch: Option<&'a (PathBuf, String)>

This box’s already-active libtorch, when fdl found one. Used when no variant is acquired, and it is what the build links against.

source: Option<SourceSpec<'a>>

Training source to fetch and build. None when the operator named an existing binary.

devices: Option<&'a [u8]>

Device ids this box will offer (--devices); None = all visible. The arch-coverage gate scopes to these: a half-covered box explicitly offering only its covered card is a working box.

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl<'a> Default for PrepareSpec<'a>

fn default() -> PrepareSpec<'a>
