Struct File 

pub struct File {
    pub mime: MimeType,
    pub source: FileSource,
    pub meta: Value,
}

A blob of non-text content attached to or emitted by a message.

Mimetype is the single source of truth for what the bytes mean. source is how to retrieve them. meta is a free-form bag for provider-specific annotations — consumers that don’t care ignore it.

Fields

mime: MimeType

source: FileSource

meta: Value

Implementations

impl File

pub fn from_bytes(bytes: impl Into<Vec<u8>>) -> File

Construct a file from raw bytes, sniffing the mimetype from content.

pub fn from_bytes_with_mime( bytes: impl Into<Vec<u8>>, mime: impl Into<String>, ) -> File

Construct a file from raw bytes with an explicit mimetype.

pub fn from_path(path: impl AsRef<Path>) -> Result<File, Error>

pub fn from_url( url: impl Into<String>, mime: Option<&str>, ) -> Result<File, Box<dyn Error + Send + Sync>>

Parse a URL. Mimetype defaults to application/octet-stream when unknown — callers can supply a hint explicitly.

pub fn with_meta(self, meta: Value) -> File

pub fn is_image(&self) -> bool

pub fn is_audio(&self) -> bool

pub fn is_video(&self) -> bool

pub fn is_document(&self) -> bool

Anything that isn’t image/audio/video is treated as a document.

Trait Implementations

impl Clone for File

fn clone(&self) -> File

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for File

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for File

fn deserialize<__D>( __deserializer: __D, ) -> Result<File, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for File

fn eq(&self, other: &File) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for File

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
