Function read_reader 

pub fn read_reader(
    reader: impl Read,
    max_bytes: usize,
) -> Result<Vec<u8>, ArtifactError>

Read one stream into bounded, fallibly allocated storage.

Observes at most max_bytes + 1 bytes to detect overflow. A blocking reader’s deadline remains caller-owned. Only interrupted reads are retried.

Errors

Returns read, allocation, or byte-limit failures. An impossible reader byte count returns IO io::ErrorKind::InvalidData.
