Struct EncoderOptions 

pub struct EncoderOptions { /* private fields */ }

Available on crate feature encoder only.

Integer option bag used to configure Draco encoding.

Options mirror the C++ Draco encoder style: global options apply to the whole geometry, while attribute options override a value for one attribute id and fall back to the global value when unset.

Common keys include quantization_bits (per-attribute precision), encoding_speed/decoding_speed, encoding_method, and prediction_scheme. Keys without an explicit setter are read and written with get_global_int / set_global_int.

Examples

use draco_core::EncoderOptions;

let mut options = EncoderOptions::new();
options.set_global_int("quantization_bits", 14); // default for all attributes
options.set_attribute_int(0, "quantization_bits", 10); // override attribute 0

assert_eq!(options.get_attribute_int(0, "quantization_bits", 0), 10);
// Attribute 1 has no override, so it falls back to the global value.
assert_eq!(options.get_attribute_int(1, "quantization_bits", 0), 14);

Implementations

impl EncoderOptions

pub fn new() -> Self

Creates options with Draco-compatible defaults.

pub fn get_encoding_speed(&self) -> i32

Returns the configured encoding speed, defaulting to 5.

pub fn get_decoding_speed(&self) -> i32

Returns the configured decoding speed target, defaulting to 5.

pub fn get_speed(&self) -> i32

Returns the maximum speed for both encoding/decoding. Matches C++ ExpertEncoder::GetSpeed() behavior.

pub fn get_prediction_scheme(&self) -> i32

Returns the forced prediction scheme, or -1 for the encoder default.

pub fn set_prediction_scheme(&mut self, value: i32)

Forces a prediction scheme by numeric Draco method id.

pub fn get_encoding_method(&self) -> Option<i32>

Returns the forced encoding method, if one was set.

pub fn set_encoding_method(&mut self, value: i32)

Forces an encoding method by numeric Draco method id.

pub fn set_version(&mut self, major: u8, minor: u8)

Sets the target Draco bitstream version.

pub fn get_version(&self) -> (u8, u8)

Returns the target Draco bitstream version, or (0, 0) for default.

pub fn set_global_int(&mut self, key: &str, value: i32)

Sets a global integer option.

pub fn get_global_int(&self, key: &str, default_val: i32) -> i32

Returns a global integer option or the supplied default.

pub fn set_attribute_int(&mut self, att_id: i32, key: &str, value: i32)

Sets an integer option for one attribute id.

pub fn get_attribute_int(&self, att_id: i32, key: &str, default_val: i32) -> i32

Returns an attribute integer option, falling back to the global value.

Trait Implementations
