Crate leptos_core

This crate contains several utility pieces that depend on multiple crates. They are all re-exported in the main leptos crate.

Re-exports

pub use typed_builder;

Structs

ForProps

Properties for the For component, a keyed list.

SuspenseProps

Props for the Suspense component, which shows a fallback while Resources are being read.

TransitionProps

Props for the Suspense component, which shows a fallback while Resources are being read.

Traits

Prop

Describes the properties of a component. This is typically generated by the Prop derive macro as part of the #[component] macro.

Functions

For

Iterates over children and displays them, keyed by the key function given.

Suspense

If any Resources are read in the children of this component, it will show the fallback while they are loading. Once all are resolved, it will render the children. If data begin loading again, falls back to fallback again.

Transition

If any Resources are read in the children of this component, it will show the fallback while they are loading. Once all are resolved, it will render the children. Unlike Suspense, this will not fall back to the fallback state if there are further changes after the initial load.

map_keyed

Function that maps a Vec to another Vec via a map function. The mapped Vec is lazy computed; its value will only be updated when requested. Modifications to the input Vec are diffed using keys to prevent recomputing values that have not changed.
