Struct stac_server::MemoryBackend

pub struct MemoryBackend { /* private fields */ }

A naive backend that stores collections and items in memory.

This backend is meant to be used for testing and toy servers, not for production.

Implementations

impl MemoryBackend

pub fn new() -> MemoryBackend

Creates a new memory backend.

Examples

use stac_server::MemoryBackend;
let backend = MemoryBackend::new();

Trait Implementations

impl Backend for MemoryBackend

fn has_item_search(&self) -> bool

Returns true if this backend has item search capabilities.

fn collections<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<Collection>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,
