Struct Invocation 

pub struct Invocation {
    pub command: Option<String>,
    pub standard_input: bool,
    pub interactive: bool,
}

How bash was given the code it runs. set refuses -i, -c and -s, so all three are settled when the shell starts and cannot have changed by the time anything reads them.

Fields

command: Option<String>

-c, with the text bash was given. Absent for any other invocation.

standard_input: bool

-s: the code arrives on standard input.

interactive: bool

-i: bash reads from a terminal, keeps history, and writes main into BASH_SOURCE for whatever is defined at the prompt.

Implementations

impl Invocation

pub fn from_a_file(&self) -> bool

Whether bash was handed a file to read, which is what makes Bash::zero a path rather than a word standing in for code bash was given directly.
