Struct BackendCheck 

pub struct BackendCheck<C = NoErrorCode> {
    pub backend: &'static str,
    pub ok: bool,
    pub code: Option<C>,
    pub error: Option<String>,
}

Available on crate feature terminal only.

Outcome of checking one backend’s connection.

Fields

backend: &'static str

The backend that was checked.

ok: bool

Whether it answered.

code: Option<C>

The stable code of the failure, null when it answered or the failure carries none.

error: Option<String>

Why it did not answer, null when it did.

Implementations

impl<C: ErrorCode> BackendCheck<C>

pub fn new(backend: &'static str, result: Result<()>) -> Self

Folds a connection attempt to backend into its outcome, coded by its chain (see error::with_code for a code read off a typed error).

Trait Implementations

impl<C: Clone> Clone for BackendCheck<C>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<C: Debug> Debug for BackendCheck<C>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<C> JsonSchema for BackendCheck<C>

where C: JsonSchema,

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl<C> Serialize for BackendCheck<C>

where C: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
