Implementations

impl Engine

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

pub fn parse(s: &str) -> Result<Engine>

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

The version a new database gets.

pub fn port(self) -> u16

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

pub fn has_root_password(self) -> bool

Whether a root password is kept beside the user’s.

pub fn has_database(self) -> bool

Whether the engine has a database name and a user to set.

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

The extension of a dump’s object (before compression).

pub fn restores_from(self, from: Engine) -> bool

Restore a dump of from into this engine?

pub fn dump_command(self) -> Vec<String>

A shell line (run inside the database’s instance, as root, with its environment) that writes a dump to stdout. Credentials come from the instance’s own environment, never from argv the daemon builds.

pub fn rotate_command(self, root: bool) -> Vec<String>

The command that makes a new password take effect inside a running database (rotate): the user’s (root: false), or MySQL’s and MariaDB’s root password. The new value arrives on stdin; the instance’s environment still holds the old one, which authenticates. The engines read their password variables only when the data directory is first made, so without this a new password would lock the apps out.

pub fn restore_command(self) -> Vec<String>

A shell line that restores a dump read from stdin, replacing what the dump holds. ISB_SOURCE_DB names the dumped database (MongoDB renames it to this one’s).

Trait Implementations

impl Eq for Engine

impl Ord for Engine

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
