Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

backend: EncodeBackendPreference

Backend preference for encode stages.

block_coding_mode: J2kBlockCodingMode

Code-block coding mode for the codestream.

progression: J2kProgressionOrder

Packet progression order.

max_decomposition_levels: Option<u8>

Optional explicit lossy decomposition level request.

rate_target: Option<J2kRateTarget>

Single codestream rate target.

quality_layers: Vec<J2kQualityLayer>

Cumulative quality layer targets.

tile_size: Option<(u32, u32)>

Optional tile width and height.

tile_part_packet_limit: Option<u16>

Optional maximum number of complete packets to place in each tile-part.

precinct_exponents: Vec<(u8, u8)>

Optional precinct exponents in COD/COC order.

marker_segments: Vec<J2kMarkerSegment>

Optional marker segments requested for the codestream.

psnr_tolerance_db: f64

Allowed PSNR target tolerance in dB.

psnr_iteration_budget: u8

Iteration budget for lossy target searches.

validation: J2kEncodeValidation

Validation policy applied before returning encoded bytes.
