Enum NameError 

pub enum NameError {
    Invalid(String),
    Taken {
        name: String,
        by: String,
    },
    ChainConflict {
        name: String,
    },
    Io(Error),
}

Why a session name was not accepted (Session::check_name). The Display text is what /saveas has always printed.

Variants

Invalid(String)

Not [a-z0-9-]{1,40} (the validate_name message).

Taken

Another saved session already has this name.

Fields

name: String

by: String

ChainConflict

A chain already has this name.

Fields

name: String

Io(Error)

The sessions directory could not be read.

Implementations

impl NameError

pub fn code(&self) -> &'static str

Stable machine code: invalid | taken | chain_conflict | io.

Trait Implementations

impl Debug for NameError

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

Formats the value using the given formatter.

impl Display for NameError

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

Formats the value using the given formatter.

impl Error for NameError

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

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

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