Crate signinum_core 

Shared traits and value types for the signinum workspace.

Codec crates use this crate to expose common pixel formats, decode outcomes, row sinks, caller-owned scratch pools, and CPU/GPU backend selection contracts without depending on each other.

Modules

accelerator

Shared accelerator runtime contracts.

backend

Backend selection and capability discovery.

batch

Shared helpers for ordered tile-batch work.

context

Reusable codec context wrappers.

device

Shared device-output request policies.

error

Common error classifications and helper error types.

passthrough

Compressed-byte passthrough eligibility checks.

pixel

Pixel layout and format descriptors.

row_sink

Row-streaming output sink trait.

sample

Integer sample type descriptors.

scale

Decode downscale options.

scratch

Caller-owned scratch pool trait.

traits

Facade traits implemented by codec crates.

types

Shared metadata and geometry types.

Constants

DEFAULT_MAX_HOST_ALLOCATION_BYTES

Default cap for host-side codec-owned allocations.

Functions

copy_tight_pixels_to_strided_output

Copy tightly packed pixel rows into a caller-provided strided output buffer.

ensure_allocation_within_cap

Returns len if it is at or below cap.

strided_output_len

Returns the number of bytes required for a strided image output buffer.

strided_output_len_capped

Returns the strided output byte length, rejecting requests over cap.

validate_strided_output_buffer

Validates that out_len and stride can hold an image output.
