Struct TxLimits 

pub struct TxLimits {
    pub max_open: usize,
    pub idle_timeout: Duration,
    pub max_lifetime: Duration,
}

The limits on open transactions.

Fields

max_open: usize

Most transactions open at once; a begin beyond it is 503.

idle_timeout: Duration

How long a transaction may sit idle before it is rolled back.

max_lifetime: Duration

How long a transaction may live from begin, however busy.

Implementations

impl TxLimits

pub fn from_env() -> Self

The limits MUSHROOMDB_TX_MAX, MUSHROOMDB_TX_TIMEOUT_SECS and MUSHROOMDB_TX_MAX_LIFETIME_SECS name. A value that is unset keeps the default; one that is not a positive integer keeps the default too and logs a warning.

pub fn from_lookup(lookup: impl Fn(&str) -> Option<String>) -> Self

TxLimits::from_env reading the three variables through lookup instead of the process environment.
