Struct opendal::layers::ImmutableIndexLayer

pub struct ImmutableIndexLayer { /* private fields */ }

ImmutableIndexLayer is used to 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::Operator;
use opendal::Scheme;

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(Scheme::Http).unwrap().layer(iil);

Implementations

impl ImmutableIndexLayer

pub fn insert(&mut self, key: String)

Insert a key into index.

pub fn extend_iter<I>(&mut self, iter: I)where
    I: IntoIterator<Item = String>,

Insert keys from iter.
