Trait View 

pub trait View: Send + Sync {
    // Required methods
    fn route(&self) -> &'static str;
    fn heading(&self) -> &'static str;
    fn param_keys(&self, ctx: &Context) -> Result<Vec<String>, ApiError>;
    fn handle_get(
        &self,
        query: &BTreeMap<String, String>,
        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 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 sections rendered from them.

Dyn Compatibility

This trait is dyn compatible.

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