pub struct ImmutableIndexLayer { /* private fields */ }
Expand description

Add an immutable in-memory index for underlying storage services.

Especially useful for services without list capability like HTTP.

Examples

use opendal::layers::ImmutableIndexLayer;
use opendal::services;
use opendal::Operator;

let mut iil = ImmutableIndexLayer::default();

for i in ["file", "dir/", "dir/file", "dir_without_prefix/file"] {
    iil.insert(i.to_string())
}

let op = Operator::from_env::<services::Http>()
    .unwrap()
    .layer(iil)
    .finish();
