Struct ProcessGuard 

pub struct ProcessGuard {
    pub stdout_reader: Option<Lines<BufReader<ChildStdout>>>,
    pub stderr_reader: Option<Lines<BufReader<ChildStderr>>>,
    pub port: u32,
    pub db_name: String,
    pub user_name: String,
    /* private fields */
}

ProcessGuard represents a postgresql process that is running in the background. once the guard is dropped the process will be killed.

Fields

stdout_reader: Option<Lines<BufReader<ChildStdout>>>

Allows users to read stdout by line for debugging.

stderr_reader: Option<Lines<BufReader<ChildStderr>>>

Allows users to read stderr by line for debugging.

port: u32

Parameters for connecting to the temporary postgresql instance.

A user shouldn’t need to use these and should call connection_string instead.

Port number that Postgresql is serving on

db_name: String

Database name to connect to.

user_name: String

Username to connect as.

Implementations

impl ProcessGuard

pub fn connection_string(&self) -> String

Get a Postgresql format connection String for the process guard.

Panics

Panics if a string file path cannot be obtained from the socket directory.

pub fn connection_string_for_db(&self, db_name: &str) -> String

Get a Postgresql format connection string for a database on this running instance.

Panics

Panics if a string file path cannot be obtained from the socket directory.

pub fn clone_database(&self, db_name: &str) -> TmpPostgrustResult<String>

Clone the current database in this running instance.

The returned connection string points at the newly-created database.

Errors

Returns an error if createdb fails to clone the current database.

Trait Implementations

impl Drop for ProcessGuard

Signal that the process needs to end.

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
