Implementations

impl VrtDataset

pub fn new(raster_x_size: u64, raster_y_size: u64) -> Self

Creates a new VRT dataset

pub fn from_bands(bands: Vec<VrtBand>) -> Result<Self>

Creates a new VRT dataset with extent from sources

Errors

Returns an error if no bands are provided

pub fn add_band(&mut self, band: VrtBand)

Adds a band to the dataset

pub fn with_geo_transform(self, geo_transform: GeoTransform) -> Self

Sets the GeoTransform

pub fn with_srs<S: Into<String>>(self, srs: S) -> Self

Sets the spatial reference system

pub fn with_block_size(self, width: u32, height: u32) -> Self

Sets the block size

pub fn with_subclass(self, subclass: VrtSubclass) -> Self

Sets the subclass

pub fn with_vrt_path<P: Into<PathBuf>>(self, path: P) -> Self

Sets the VRT file path

pub fn validate(&self) -> Result<()>

Validates the dataset

Errors

Returns an error if the dataset is invalid

pub fn band_count(&self) -> usize

Gets the number of bands

pub fn get_band(&self, index: usize) -> Option<&VrtBand>

Gets a band by index (0-based)

pub fn get_band_mut(&mut self, index: usize) -> Option<&mut VrtBand>

Gets a mutable reference to a band by index (0-based)

pub fn extent(&self) -> PixelRect

Gets the extent as a pixel rectangle

pub fn effective_block_size(&self) -> (u32, u32)

Gets the effective block size (uses dataset default or falls back to 256x256)

pub fn merge_geo_transforms(&mut self) -> Result<()>

Merges GeoTransforms from multiple sources to create a unified transform

Errors

Returns an error if sources have incompatible GeoTransforms

pub fn primary_data_type(&self) -> Option<RasterDataType>

Gets the data type of the first band

pub fn has_uniform_data_type(&self) -> bool

Checks if all bands have the same data type

Trait Implementations

impl Clone for VrtDataset

fn clone(&self) -> VrtDataset

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VrtDataset

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VrtDataset

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for VrtDataset

fn eq(&self, other: &VrtDataset) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for VrtDataset

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
