Struct ContentType 

pub struct ContentType {
    pub type_: String,
    pub subtype: String,
    pub params: HashMap<String, String>,
}

Parsed Content-Type: header value.

Fields

type_: String

Top-level type (“text”, “multipart”, “application”, …), lowercased.

subtype: String

Subtype (“plain”, “html”, “alternative”, “mixed”, “calendar”, …), lowercased.

params: HashMap<String, String>

Lowercased parameter map (boundary, charset, name, …). Values are RFC 2231-decoded when the on-wire shape was name*=charset''pct-encoded.

Implementations

impl ContentType

pub fn default_for_missing_header() -> Self

Default per RFC 2045 §5.2 when no Content-Type is present: text/plain; charset=us-ascii.

pub fn parse(value: &str) -> Self

Parse from raw header value (e.g. multipart/mixed; boundary="xyz").

pub fn is_multipart(&self) -> bool

true if this is a multipart/* type.

pub fn mime_type(&self) -> String

Convenience: "<type>/<subtype>".

pub fn boundary(&self) -> Option<&str>

boundary= parameter for multipart parts. None for non-multipart or malformed multipart.

pub fn charset(&self) -> &str

charset= parameter for text/* parts. Defaults to “us-ascii” per RFC 2045 §5.2 when absent.

pub fn name(&self) -> Option<&str>

name= parameter — historical attachment filename source. See also Content-Disposition filename=.
