Module model 

Request schema, validation and profile-source loading.

Budgets

LegacyGrid

ProfileData

Loaded profile data, before interpolator preparation.

ProfileEstimate

Pre-read memory estimate for loading and preparing one profile.

ProfileSpec

SessionRequest

Enums

CrsIdentity

How the terrain CRS is established equal to the session EPSG. Never inferred silently.

Constants

LEGACY_JSON_PEAK_FACTOR

Bytes per JSON byte assumed for a fully parsed legacy request plus its preparation. Derived from the worst-case textual densities (e.g. 0, -> 16-byte Option<f64>, [1,2,3], -> 24-byte simplex plus prepared triangle and bulk-load copy) with 2x Vec growth slack. A conservative heuristic, not a proof: use binary sources where a tight pre-read estimate matters.

MAX_BINARY_BYTES

MAX_JSON_BYTES

MAX_PROFILE_PIXELS

MAX_THREADS

READ_CHUNK_BYTES

Chunk size of the streaming binary decoder.

SESSION_SCHEMA

Functions

id_key

Case-insensitive identity of an id (two ids with equal keys collide on NTFS).

read_json

resolve

validate_id

Ids name output directories, so they must be path-safe on Linux and Windows/NTFS (including drvfs/SMB): [A-Za-z0-9_.-]{1,64}, not ./.., no trailing ., no Windows device name. Uniqueness is checked case-insensitively by the caller (id_key).
