Struct TileProcessor 

pub struct TileProcessor { /* private fields */ }

Base struct for tile processors that wrap a single upstream source.

This struct provides:

• Storage for the upstream source
• Cloned metadata (parameters, TileJSON, traversal) from the source
• Builder pattern for modifying metadata
• Accessor methods for implementation convenience

Processors should embed this struct and delegate trait method implementations to its methods where appropriate.

Implementations

impl TileProcessor

pub fn new(name: impl Into<String>, source: Box<dyn TileSource>) -> Self

Creates a new processor wrapping the given source.

Clones metadata (parameters, TileJSON, traversal) from the source, which can then be modified via builder methods.

Arguments

• name - Human-readable name for this processor (e.g., “filter”, “converter”)
• source - The upstream tile source to wrap

pub fn with_parameters(self, parameters: TileSourceMetadata) -> Self

Builder method to override the parameters.

Use this when the processor modifies spatial extent, compression, or format.

pub fn with_tilejson(self, tilejson: TileJSON) -> Self

Builder method to override the TileJSON metadata.

Use this when the processor modifies metadata (e.g., updating attribution, bounds).

pub fn with_traversal(self, traversal: Traversal) -> Self

Builder method to override the traversal hint.

Use this when the processor has a preferred read order different from its source.

pub fn name(&self) -> &str

Returns the processor’s name.

pub fn source(&self) -> &dyn TileSource

Returns the upstream source as a trait object reference.

pub fn source_mut(&mut self) -> &mut Box<dyn TileSource>

Returns a mutable reference to the boxed source.

Use this when you need to call mutable methods on the source (e.g., override_compression).

pub fn parameters(&self) -> &TileSourceMetadata

Returns the (potentially modified) parameters.

pub fn tilejson(&self) -> &TileJSON

Returns the (potentially modified) TileJSON.

pub fn traversal(&self) -> &Traversal

Returns the (potentially modified) traversal hint.

pub fn parameters_mut(&mut self) -> &mut TileSourceMetadata

Returns a mutable reference to the parameters.

Use this to modify parameters after construction.

pub fn tilejson_mut(&mut self) -> &mut TileJSON

Returns a mutable reference to the TileJSON.

Use this to modify metadata after construction.

pub fn traversal_mut(&mut self) -> &mut Traversal

Returns a mutable reference to the traversal hint.

Use this to modify traversal after construction.

Trait Implementations

impl Debug for TileProcessor

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

Formats the value using the given formatter.
