Enum Result

pub enum Result<T> {
    Ok(T),
    Err(Error),
}

Result is a type that represents either success (Ok) or failure (Err). This is simple version of Result type to comply XRPL Hooks Webassembly restrictions

Variants

Ok(T)

Contains the success value

Err(Error)

Contains the error value

Implementations

impl<T> Result<T>

pub fn expect(self, msg: &[u8]) -> T

Returns the contained Ok value, consuming the self value.

Rollbacks

Rollbacks if the value is an Err, with a rollback message and error code.

pub fn unwrap(self) -> T

Returns the contained Ok value, consuming the self value.

Because this function may rollback, its use is generally discouraged. Instead, prefer to use pattern matching and handle the Err case explicitly.

Rollbacks

Rollbacks if the value is an Err, with a “error” and error code provided by the Err’s value.

pub unsafe fn unwrap_unchecked(self) -> T

Returns the contained Ok value, consuming the self value, without checking that the value is not an Err.

Safety

Calling this method on an Err is undefined behavior.

pub const fn is_ok(&self) -> bool

Returns true if the result is Ok.

pub const fn is_err(&self) -> bool

Returns true if the result is Err.
