我使用该法典将国防军改为les子:
// Combine vectors into a new vector of tuples
let combined_data: Vec<(i64, i32, f64, f64)> =
timestamp
.into_iter()
.zip(side.into_iter())
.zip(size.into_iter())
.zip(price.into_iter())
.map(|(((ts, s), sz), pr)| (ts, s, sz, pr))
.collect();
我也为12栏提供了版本。 没有人能够提出一种办法,以笼统的方式转换任何栏目?

izip!(timestamp, side, size, price).collect::<Vec<_>>() // Vec of 4-tuples
即便在您的榜样中,你也只需要into_iter(),timest;zip。 这种方法仅要求其论点为IntoIterator,而不是Iterator。
