Struct DeviceSignatureTable 

pub struct DeviceSignatureTable { /* private fields */ }

Collection of signatures loaded from a directory.

Implementations

impl DeviceSignatureTable

pub fn builtins() -> Result<Self, String>

Load the signatures compiled into this crate.

This reads NO files. It parses the DeviceSignature::BUILTIN_BLACKWELL_120 string that include_str! baked into the binary, sorts by id, and wraps. Self::load_dir is the filesystem path; this is the no-filesystem fallback used by backend projections before external Tier-B directories are available.

The parse is memoized process-wide, because it is a pure function of compile-time constants and backend projections call it on every dispatch. Prefer Self::builtins_ref on a hot path: this clones the memoized table so callers that need an owned value keep working.

Errors

Returns an actionable error when the compiled-in signature is invalid.

pub fn builtins_ref() -> Result<&'static Self, String>

Borrow the process-wide memoized builtin signature table.

Errors

Returns an actionable error when the compiled-in signature is invalid.

pub fn load_dir(dir: impl AsRef<Path>) -> Result<Self, String>

Load every *.toml signature file in dir.

Errors

Returns an actionable error when the directory cannot be read, a file cannot be read, or any signature is invalid.

pub fn signatures(&self) -> &[DeviceSignature]

Borrow all loaded signatures in stable id order.

pub fn get(&self, id: &str) -> Option<&DeviceSignature>

Find a signature by id.

pub fn find_architecture_generation( &self, generation: u32, ) -> Option<&DeviceSignature>

Find the best signature for a backend-reported architecture generation.

pub fn find_device_name(&self, device_name: &str) -> Option<&DeviceSignature>

Find the best signature for a backend-reported device name.

pub fn apply_generation_to_profile( &self, generation: u32, profile: DeviceProfile, ) -> DeviceProfile

Apply a generation signature to profile when one is known.

pub fn apply_device_name_to_profile( &self, device_name: &str, profile: DeviceProfile, ) -> DeviceProfile

Apply a device-name signature to profile when one is known.
