Crate async_geotiff

Expand description

async-geotiff: pure-Rust async COG → XYZ tile renderer.

Style inputs use Raster Style 3.0 JSON/Q3; see style::TileStyle.

Modules§

bounds: Spatial envelopes and pixel-to-world affine transforms.
crs: Coordinate reference system identifiers.
error: Errors shared by readers, renderers and request controls.
io: Asynchronous COG access, decoded block caching and source metadata.
mosaic: Multi-source pixel-level mosaics with bounded asset discovery and reduction.
pixel: Typed pixel arrays, validity masks and georeferenced images.
render: Raster Style render plans, expressions, color maps and image encoding.
request: Request admission, deadline, and cooperative cancellation.
resource: Shared accounting for active library working buffers, separate from caches and caller-owned completed outputs. Individual reservations stay nonblocking: waiting while holding other allocations can deadlock a multi-stage pipeline. Public tile requests use a shared admission gate. On memory pressure the entire failed attempt unwinds before one exclusive retry, inside the original request deadline. This drains competing requests without raising the byte cap.
style: Validated Raster Style 3.0 JSON/Q3 documents and compilation.
tiler: Top-level orchestrator: HTTP request → tile bytes.
tms: Supported tile matrix sets and checked tile coordinates.
warp: Coordinate reprojection and spatial resampling of raster images.

perf_trace: Include instrumentation tokens only when perf-tracing is enabled.
