Enum StdinData 

pub enum StdinData {
    Bytes(Vec<u8>),
    Reader(Box<dyn Read + Send + Sync>),
}

Input data to feed to a child process’s stdin.

Construct via the From impls — accepts Vec<u8>, String, &str, &[u8], or Box<dyn Read + Send + Sync + 'static>. Use from_reader() for the streaming case.

Retry semantics

• Bytes: owned, reusable. If the Cmd is configured to retry, each attempt re-feeds the same bytes.
• Reader: one-shot. The first attempt consumes the reader. If a retry is needed, no stdin is available and the second attempt will likely behave differently. Avoid .retry() with a streaming reader unless you understand this.

Variants

Bytes(Vec<u8>)

Reader(Box<dyn Read + Send + Sync>)

Implementations

impl StdinData

pub fn from_reader<R>(reader: R) -> StdinData

where R: Read + Send + Sync + 'static,

Wrap any Read source as one-shot streaming stdin.

pub fn is_reusable(&self) -> bool

Whether this stdin can be safely re-used across retries.
