Crate wasm_smtp_component 

wasm-smtp-component

WASM Component Model interface for wasm-smtp.

This crate exports the smtp-send WIT interface defined in wit/smtp.wit, allowing any language with WIT bindings to send email through wasm-smtp without writing Rust.

Building

# Requires cargo-component and the wasm32-wasip2 target.
cargo component build --target wasm32-wasip2 -p wasm-smtp-component
# Output: target/wasm32-wasip2/debug/wasm_smtp_component.wasm

Running tests on native

cargo test -p wasm-smtp-component

Credential security

Credentials cross the host-component boundary as plain WIT strings on every send call. They are not retained by the component between calls. See docs/src/adapters/component-model.md for the full threat model.
