Struct pgdo::runtime::Runtime

pub struct Runtime {
    pub bindir: PathBuf,
    pub version: Version,
}

Fields

bindir: PathBuf

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

version: Version

Version of this runtime.

Implementations

impl Runtime

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

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.execute("pg_ctl").arg("--version").output()?;

Panics

Panics if it’s not possible to calculate PATH; see env::join_paths.

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.command("bash").arg("-c").arg("echo hello").output();

Panics

Panics if it’s not possible to calculate PATH; see env::join_paths.

Trait Implementations

impl Clone for Runtime

fn clone(&self) -> Runtime

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Runtime

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

Formats the value using the given formatter.

impl PartialEq for Runtime

fn eq(&self, other: &Runtime) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Strategy for Runtime

Use a single runtime as a strategy.

fn runtimes(&self) -> Runtimes<'_>

This runtime itself is the only runtime known to this strategy.

fn select(&self, version: &PartialVersion) -> Option<Runtime>

Return this runtime if the given version constraint is compatible.

fn fallback(&self) -> Option<Runtime>

Always return this runtime.
