Trait View 

pub trait View: Send + Sync {
    // Required methods
    fn route(&self) -> &'static str;
    fn heading(&self) -> &'static str;
    fn listed(&self) -> bool;
    fn param_keys(&self, ctx: &Context) -> Result<Vec<String>, ApiError>;
    fn handle_get(
        &self,
        query: &BTreeMap<String, String>,
        ctx: &Context,
    ) -> Result<String, ApiError>;
    fn handle_action(
        &self,
        name: &str,
        query: &BTreeMap<String, String>,
        body: &str,
        ctx: &Context,
    ) -> Result<String, ApiError>;
}

The object-safe façade the router dispatches through, as crate::Table is for tables. A blanket implementation covers every ViewLogic, so nothing outside this module implements it.

Required Methods

fn route(&self) -> &'static str

The route segment, from ViewLogic::name.

fn heading(&self) -> &'static str

The shell’s heading, from ViewLogic::title.

fn listed(&self) -> bool

Whether the switcher lists this view, from ViewLogic::in_switcher.

fn param_keys(&self, ctx: &Context) -> Result<Vec<String>, ApiError>

The keys of the parameters this view declares, which the server checks against the ones the address itself uses.

fn handle_get( &self, query: &BTreeMap<String, String>, ctx: &Context, ) -> Result<String, ApiError>

GET /api/views/<view>: the parameters, what they resolved to, and the page rendered from them.

fn handle_action( &self, name: &str, query: &BTreeMap<String, String>, body: &str, ctx: &Context, ) -> Result<String, ApiError>

POST /api/views/<view>/actions/<name>: write what the form asks for, and answer with the sentence saying so.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
