Struct DbPool

pub struct DbPool(pub Arc<PgPool>);

Tuple Fields§

§0: Arc<PgPool>

Trait Implementations§

impl<S> FromRequestParts<S> for DbPool
where S: Send + Sync,

自定义提取器，提取数据库连接池对象

type Rejection = DbError

If the extractor fails it’ll use this “rejection” type. A rejection is a kind of error that can be converted into a response.

async fn from_request_parts( parts: &mut Parts, state: &S, ) -> Result<Self, Self::Rejection>

Perform the extraction.
