#MoonMIME
Bounded, byte-preserving MIME security inspection for MoonBit.
let message = @moonmime.parse(
b"Subject: hello\r\nContent-Type: text/plain\r\n\r\nMoonBit",
)
inspect(message.root.media_type.essence(), content="text/plain")v0.2 adds a deterministic security audit layer over ordered and folded headers, recursive multipart/*, direct message/rfc822, Base64, Quoted-Printable, RFC 2047 encoded-words, and RFC 2231 extended parameters. Findings identify parser ambiguity and unsafe extraction metadata with a stable code, severity, entity path, and exact source byte range.
The parser does no network or filesystem I/O. The separate Native CLI can inspect or audit a local .eml; audit --fail-on high supports quarantine/CI policy without decoding or extracting attachments.
See the repository README for the full guide, scope, resource limits, security model, standards matrix, and testing instructions. Licensed under Apache-2.0.
audit
Parse and audit untrusted message structure without decoding attachments.
audit_json
Parse and return stable moonmime.audit.v1 JSON for security pipelines.
decode_body
fn decode_body(message : InternetMessage, path : Array[Int], mode? : ParseMode, max_output? : Int) -> Bytes raise MimeErrorDecode a selected entity body after validating its source range.
edge_limits
Re-export the smaller edge-oriented limits through the root package.
inspect_json
fn inspect_json(input : Bytes, mode? : ParseMode, limits? : ResourceLimits) -> String raise MimeErrorParse and return the stable v1 JSON inspection report.
inspect_text
fn inspect_text(input : Bytes, mode? : ParseMode, limits? : ResourceLimits) -> String raise MimeErrorParse and return the human-oriented entity summary.
parse
Parse with secure resource defaults and strict RFC-oriented behavior.
parse_with
fn parse_with(input : Bytes, mode : ParseMode, limits : ResourceLimits) -> InternetMessage raise MimeErrorParse with explicit recovery behavior and resource limits.
secure_limits
Re-export the secure default limits through the root package.
