Struct DriverConfig 

pub struct DriverConfig {
    pub payload_byte_limit: usize,
    pub datagram_count: usize,
}

Config a load generator reads to shape its output to this timeline’s SUT. first_sample_config samples it beside datadog.yaml from one draw, so the generator and the SUT are driven together.

Fields

payload_byte_limit: usize

Max bytes a generator packs into one datagram, the smaller of the SUT’s sampled receive buffer and PAYLOAD_BYTE_LIMIT. A datagram this size fits one read, so the SUT never truncates a line mid-token.

datagram_count: usize

Datagrams a driver invocation ships this timeline.

Implementations

impl DriverConfig

pub fn to_yaml(&self) -> Result<String>

Render self as a driver.yaml string.

Errors

Returns an error if serialization fails.

pub fn read(config_dir: &Path) -> Result<Self>

Read the driver config from the driver.yaml that first_sample_config wrote to config_dir.

Errors

Returns an error if the config is unreadable or is not valid YAML with an integer payload_byte_limit.
