Struct Exec 

pub struct Exec {
    pub program: OsString,
    pub args: Vec<OsString>,
    pub env: Vec<(OsString, OsString)>,
    pub cwd: PathBuf,
    pub stdin: Option<Zeroizing<Vec<u8>>>,
}

One spawn request, fully constructed before anything runs.

Fields

program: OsString

The program to spawn.

args: Vec<OsString>

Its arguments; a secret never appears here.

env: Vec<(OsString, OsString)>

The constructed environment, applied over env_clear.

cwd: PathBuf

The working directory.

stdin: Option<Zeroizing<Vec<u8>>>

Bytes written to the child’s stdin, then closed. Scrubbed on drop, because this is the channel a credential travels on.

Implementations

impl Exec

pub fn echo(&self) -> String

The one + -prefixed echo line: a rendering of the typed argument list, produced here and never by shell tracing.

Trait Implementations

impl Debug for Exec

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

Everything but stdin: that field carries a credential, and a derived rendering would put it in whatever formatted an Exec.
