Crate shapefile_wasm 

Reads and writes ESRI Shapefiles from GeoJSON, entirely in memory.

The public surface is deliberately small: hand it GeoJSON, get back the raw .shp / .shx / .dbf byte buffers — or hand it those bytes and get GeoJSON back. Zipping, projection files and anything browser-shaped is left to the TypeScript layer, which keeps the wasm binary small and this core usable from plain Rust too.

Entry points

• write_shapefile / write_shapefile_from_json — GeoJSON to bytes
• read_shapefile / read_shapefile_to_json — bytes to GeoJSON
• set_panic_hook — route panics to console.error while debugging

Modules

error

geometry

Turns parsed GeoJSON geometries into concrete shapefile shapes.

input

Parsing of the GeoJSON that comes in from JavaScript.

read

Reads shapefile components back into GeoJSON.

schema

Derives a dBase table schema from GeoJSON properties.

Structs

FieldReport

What one column became in the .dbf, so callers can report renames.

Options

Caller-tunable knobs. Every field is optional; the defaults suit most data.

ShapefileParts

The generated shapefile components, plus what was inferred along the way.

Functions

read_shapefile

Reads a shapefile back into a GeoJSON FeatureCollection.

read_shapefile_to_json

Reads a shapefile and returns GeoJSON as a string.

set_panic_hook

Routes Rust panics to console.error with a readable message and stack.

write_shapefile

Builds a shapefile from a GeoJSON value passed straight across the wasm boundary.

write_shapefile_from_json

Builds a shapefile from a GeoJSON string.
