Struct GlbSizeProjection 

pub struct GlbSizeProjection {
    pub total_bytes: u64,
    pub bin_bytes: u64,
    pub fits_single_glb: bool,
    pub stats: GltfStats,
}

Projected size of the single-GLB export for a model, computed from pass 1 only (no output allocation) — issue #1516. A caller uses it to pick single GLB vs multi-buffer glTF (export_gltf_streaming) WITHOUT the historical “attempt the GLB, catch the 4 GiB panic, re-run as multi-buffer” dance.

Fields

total_bytes: u64

Projected total GLB container size in bytes (padded JSON + padded BIN + chunk headers). Exact when it fits; a lower bound once oversize (the truncated buffer numbers in the discarded JSON make it marginally short).

bin_bytes: u64

Projected BIN payload (positions + normals + indices), the value checked against the glTF 4 GiB per-buffer limit. Always exact (u64, no truncation).

fits_single_glb: bool

false when the projected GLB would exceed the glTF 32-bit (4 GiB) limit — route to export_gltf_streaming (multi-buffer) instead.

stats: GltfStats

Coverage of the projected export (post content-dedup mesh/vertex/tri counts).
