Enum csv::QuoteStyle[−][src]

[−]
pub enum QuoteStyle {
    Always,
    Necessary,
    NonNumeric,
    Never,
    // some variants omitted
}
[−]

The quoting style to use when writing CSV data.

Variants

Always
[−]

This puts quotes around every field. Always.

Necessary
[−]

This puts quotes around fields only when necessary.

They are necessary when fields contain a quote, delimiter or record terminator. Quotes are also necessary when writing an empty record (which is indistinguishable from a record with one empty field).

This is the default.

NonNumeric
[−]

This puts quotes around all fields that are non-numeric. Namely, when writing a field that does not parse as a valid float or integer, then quotes will be used even if they aren’t strictly necessary.

Never
[−]

This never writes quotes, even if it would produce invalid CSV data.
