Enum QuoteStyle 

pub enum QuoteStyle {
    Necessary,
    Always,
    NonNumeric,
    Never,
}

Available on crate features csv or json only.

Quote style indicating when to insert quotes around a field.

Variants

Necessary

Quote fields only when necessary.

Quotes are necessary when fields contain a quote, separator or record terminator. Quotes are also necessary when writing an empty record (which is indistinguishable from arecord with one empty field). This is the default.

Always

Quote every field. Always.

NonNumeric

Quote non-numeric fields.

When writing a field that does not parse as a valid float or integer, quotes will be used even if they aren’t strictly necessary.

Never

Never quote any fields, even if it would produce invalid CSV data.
