Struct GenContext 

pub struct GenContext<'a> {
    pub rng: Rng,
    pub locales: &'a [&'a Locale],
    pub modifier: &'a str,
    pub identity: Option<&'a Identity>,
    pub tz_offset_minutes: i32,
    pub since: i64,
    pub until: i64,
    pub range: Option<(i64, i64)>,
    pub ordering: Ordering,
    pub zipf: Option<ZipfSpec>,
    pub numeric: Option<f64>,
}

Generation context — replaces globals and rigid GenFn params.

Fields

rng: Rng

locales: &'a [&'a Locale]

modifier: &'a str

identity: Option<&'a Identity>

tz_offset_minutes: i32

since: i64

until: i64

range: Option<(i64, i64)>

Per-field range override, resolved (both bounds filled).

ordering: Ordering

Monotonic ordering: Asc/Desc use record number for position.

zipf: Option<ZipfSpec>

Zipf distribution over the range. None = uniform.

numeric: Option<f64>

Raw numeric value — set by numeric generators, read by aggregators.

Implementations

impl<'a> GenContext<'a>

pub fn locale(&mut self) -> &'a Locale

Locale locked to Identity when ctx active, otherwise random.

pub fn pick_locale(&mut self) -> &'a Locale

Always random locale pick (ignores identity).

pub fn tz_log(&self, buf: &mut String)

TZ offset for Apache log: “+HHMM” / “-HHMM”

pub fn tz_iso(&self, buf: &mut String)

TZ offset for ISO 8601: “Z” or “+HH:MM” / “-HH:MM”
