Trait FromRequestParts 

pub trait FromRequestParts<S>: Sized {
    type Error;

    // Required method
    fn from_request_parts(
        parts: &RequestParts,
        state: &S,
    ) -> Result<Self, Self::Error>;
}

从请求中提取数据的 trait

类似于 Axum 的 FromRequestParts trait，用于从 HTTP 请求中提取数据。

Required Associated Types

type Error

提取过程中可能发生的错误

Required Methods

fn from_request_parts( parts: &RequestParts, state: &S, ) -> Result<Self, Self::Error>

从请求中提取数据

参数

• parts - 请求上下文
• state - 应用状态

Dyn Compatibility

This trait is not dyn compatible.

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