Implementations§

Source§

impl ContentType

Source

pub const SNIFFED_LENGTH: usize = 12

The first bytes sniff and matches need.

Source

pub fn parse(text: &str) -> Result<Self>

Source

pub fn octet_stream() -> Self

Source

pub fn as_str(&self) -> &str

Source

pub fn sniff(start: &[u8]) -> Option<Self>

None when the bytes start like no type this checks, which a text file does.

Source

pub fn matches(&self, start: &[u8]) -> bool

Source

pub fn served(&self) -> (&str, Disposition)

How a download is sent: its type, and inline only when that cannot run as a page.
