Struct TilesConvertReader 

pub struct TilesConvertReader { /* private fields */ }

Reader adapter that applies coordinate transforms, bbox filtering, and optional compression changes on-the-fly.

This type implements TileSource, so it can be used anywhere a normal reader is expected. Use TilesConvertReader::new_from_reader to wrap an existing reader.

Implementations

impl TilesConvertReader

pub fn new_from_reader( reader: Arc<Box<dyn TileSource>>, cp: TilesConverterParameters, ) -> Result<TilesConvertReader>

Wraps an existing reader so that reads are transformed according to cp.

Updates the internal TileSourceMetadata and TileJSON to reflect the chosen bbox, axis transforms, and compression.

Errors

Propagates errors from querying/deriving parameters or updating metadata.

Trait Implementations

impl Debug for TilesConvertReader

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

Formats the value using the given formatter.

impl TileSource for TilesConvertReader

fn source_type(&self) -> Arc<SourceType>

Returns the source type (container format, processor name, or composite).

fn metadata(&self) -> &TileSourceMetadata

Returns runtime metadata describing the tiles this source will produce.

fn tilejson(&self) -> &TileJSON

Returns the TileJSON metadata for this tileset.

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Fetches a single tile at the given coordinate.

fn boxed(self) -> Box<dyn TileSource>

where Self: Sized + 'static,

Converts self into a boxed trait object for dynamic dispatch.
