Struct DensityMeshGenerator

pub struct DensityMeshGenerator { /* private fields */ }

Generate density mesh with region changes. For now it recalculates mesh from whole density map data.

Implementations

impl DensityMeshGenerator

pub fn new( points: Vec<Coord>, map: DensityMap, settings: GenerateDensityMeshSettings, ) -> Self

Create new generator.

Arguments

• points - Initial points.
• map - Density map.
• settings - Settings.

Returns

New generator instance.

pub fn map(&self) -> &DensityMap

Get inner density map.

pub fn mesh(&self) -> Option<&DensityMesh>

Get inner density mesh if one is already generated.

pub fn into_mesh(self) -> Option<DensityMesh>

pub fn in_progress(&self) -> bool

Tells if there are changes left to process.

pub fn progress(&self) -> (usize, usize, Scalar)

Get processing progress.

Returns

(current, limit, percentage)

pub fn change_map( &mut self, col: usize, row: usize, width: usize, height: usize, data: Vec<u8>, settings: GenerateDensityMeshSettings, ) -> Result<(), DensityMapError>

Add map change to the pending queue.

Arguments

• col - Density map destination column.
• row - Density map destination row.
• width - Source data unscaled width.
• height - Source data unscaled height.
• data - Source data buffer.
• settings - Density mesh generation settings applied for this change.

Returns

Ok if successful or density map error.

pub fn process(&mut self) -> Result<ProcessStatus, GenerateDensityMeshError>

Process penging change.

Returns

Result with process status when ok, otherwise error.

pub fn process_wait(&mut self) -> Result<(), GenerateDensityMeshError>

Process incoming changes until none is left to do.

Returns

Ok or generation error.

pub fn process_wait_timeout( &mut self, timeout: Duration, ) -> Result<ProcessStatus, GenerateDensityMeshError>

Process incoming changes until none is left to do.

Arguments

• timeout - Duration of time that processing can take.

Returns

Process status or generation error.

pub fn process_wait_tracked<F>( &mut self, f: F, ) -> Result<(), GenerateDensityMeshError>

where F: FnMut(usize, usize, Scalar),

Process incoming changes until none is left to do.

Arguments

• f - Callback triggered on every processing step. Signature: fn(progress, limit, factor).

Returns

Ok or generation error.

pub fn process_wait_timeout_tracked<F>( &mut self, f: F, timeout: Duration, ) -> Result<ProcessStatus, GenerateDensityMeshError>

where F: FnMut(usize, usize, Scalar),

Process incoming changes until none is left to do.

Arguments

• f - Callback triggered on every processing step. Signature: fn(progress, limit, factor).
• timeout - Duration of time that processing can take.

Returns

Process status or generation error.

Trait Implementations

impl Clone for DensityMeshGenerator

fn clone(&self) -> DensityMeshGenerator

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DensityMeshGenerator

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DensityMeshGenerator

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DensityMeshGenerator

fn eq(&self, other: &DensityMeshGenerator) -> 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 DensityMeshGenerator

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
