Struct ContentMetadata 

pub struct ContentMetadata {
    pub name: String,
    pub mime_type: Option<String>,
    pub len: Option<u64>,
    pub modified_millis: Option<u64>,
    pub identifier: String,
}

Everything a provider can state about a piece of content without reading it.

Fields

name: String

Display name, usually the last path or URI component.

mime_type: Option<String>

MIME type when the provider reports one.

len: Option<u64>

Byte length when the provider reports one.

modified_millis: Option<u64>

Last-modified time in milliseconds since the Unix epoch, when known.

identifier: String

Provider-scoped identifier: a path, a content:// URI, a blob name. Not guaranteed to be openable outside its provider.
