Struct Error 

pub struct Error {
    pub message: String,
}

A LevelDB error, just containing the error string provided by LevelDB.

Fields

message: String

Implementations

impl Error

pub fn new(message: String) -> Error

create a new Error, using the String provided

pub unsafe fn new_from_char(message: *const c_char) -> Error

create an error from a c-string buffer.

This method is unsafe because the pointer must be valid and point to heap. The pointer will be passed to free!

Safety

The caller must ensure that:

• message is a valid pointer to a null-terminated C string
• The C string is valid UTF-8
• The memory pointed to by message was allocated by LevelDB and can be safely freed

Trait Implementations

impl Debug for Error

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

impl Display for Error

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

impl Error for Error

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn provide<'a>(&'a self, request: &mut Request<'a>)
