Struct postgresfixture::runtime::Runtime

pub struct Runtime {
    pub bindir: Option<PathBuf>,
}

Fields

bindir: Option<PathBuf>

Path to the directory containing the pg_ctl executable and other PostgreSQL binaries.

Can be omitted (i.e. None) to search PATH only.

Implementations

impl Runtime

pub fn find<T: AsRef<OsStr> + ?Sized>(path: &T) -> Vec<Self>

Find runtimes on the given path.

Parses input according to platform conventions for the PATH environment variable. See env::split_paths for details.

pub fn find_on_path() -> Vec<Self>

Find runtimes on PATH (environment variable).

pub fn new<P: AsRef<Path>>(bindir: P) -> Self

pub fn version(&self) -> Result<Version, VersionError>

Get the version number of PostgreSQL.

https://www.postgresql.org/support/versioning/ shows that version numbers are not SemVer compatible, so we have to parse them ourselves.

pub fn execute<T: AsRef<OsStr>>(&self, program: T) -> Command

Return a Command prepped to run the given program in this PostgreSQL runtime.

let version = Runtime::default().execute("pg_ctl").arg("--version").output().unwrap();

pub fn command<T: AsRef<OsStr>>(&self, program: T) -> Command

Return a Command prepped to run the given program with this PostgreSQL runtime at the front of PATH. This is very similar to Self::execute except it does not qualify the given program name with Self::bindir.

let version = Runtime::default().command("bash").arg("-c").arg("echo hello").output().unwrap();

Trait Implementations
