Trait actix_web::dev::FromParam
[−]
[src]
pub trait FromParam: Sized { type Err: ResponseError; fn from_param(s: &str) -> Result<Self, Self::Err>; }
A trait to abstract the idea of creating a new instance of a type from a path parameter.
Associated Types
type Err: ResponseError
The associated error which can be returned from parsing.
Required Methods
fn from_param(s: &str) -> Result<Self, Self::Err>
Parses a string s to return a value of this type.
Implementations on Foreign Types
impl FromParam for PathBuf[src]
Creates a PathBuf from a path parameter. The returned PathBuf is
percent-decoded. If a segment is equal to "..", the previous segment (if
any) is skipped.
For security purposes, if a segment meets any of the following conditions,
an Err is returned indicating the condition met:
- Decoded segment starts with any of:
.(except..),* - Decoded segment ends with any of:
:,>,< - Decoded segment contains any of:
/ - On Windows, decoded segment contains any of: ''
- Percent-encoding results in invalid UTF8.
As a result of these conditions, a PathBuf parsed from request path parameter is
safe to interpolate within, or use as a suffix of, a path without additional
checks.
