Struct phonenumber::metadata::Format
[−]
[src]
pub struct Format { /* fields omitted */ }
Description of a phone number format.
Methods
impl Format
[src]
pub fn pattern(&self) -> &CachedRegex
[src]
A regex that is used to match the national (significant) number. For example, the pattern "(20)(\d{4})(\d{4})" will match number "2070313000", which is the national (significant) number for Google London.
Note the presence of the parentheses, which are capturing groups what specifies the grouping of numbers.
pub fn format(&self) -> &str
[src]
Specifies how the national (significant) number matched by pattern should be formatted.
Using the same example as above, format could contain "$1 $2 $3", meaning that the number should be formatted as "20 7031 3000".
Each $x are replaced by the numbers captured by group x in the regex specified by pattern.
pub fn leading_digits(&self) -> &[CachedRegex]
[src]
A regex that is used to match a certain number of digits at the beginning of the national (significant) number. When the match is successful, the accompanying pattern and format should be used to format this number. For example, if leading_digits="[1-3]|44", then all the national numbers starting with 1, 2, 3 or 44 should be formatted using the accompanying pattern and format.
The first leadingDigitsPattern matches up to the first three digits of the national (significant) number; the next one matches the first four digits, then the first five and so on, until the leadingDigitsPattern can uniquely identify one pattern and format to be used to format the number.
In the case when only one formatting pattern exists, no leading_digits_pattern is needed.
pub fn national_prefix(&self) -> Option<&str>
[src]
Specifies how the national prefix ($NP) together with the first group ($FG) in the national significant number should be formatted in the NATIONAL format when a national prefix exists for a certain country.
For example, when this field contains "($NP$FG)", a number from Beijing, China (whose $NP = 0), which would by default be formatted without national prefix as 10 1234 5678 in NATIONAL format, will instead be formatted as (010) 1234 5678; to format it as (0)10 1234 5678, the field would contain "($NP)$FG". Note $FG should always be present in this field, but $NP can be omitted. For example, having "$FG" could indicate the number should be formatted in NATIONAL format without the national prefix.
This is commonly used to override the rule specified for the territory in the XML file.
When this field is missing, a number will be formatted without national prefix in NATIONAL format. This field does not affect how a number is formatted in other formats, such as INTERNATIONAL.
pub fn is_national_prefix_optional(&self) -> bool
[src]
Whether the national_prefix is optional when formatting.
pub fn domestic_carrier(&self) -> Option<&str>
[src]
Specifies how any carrier code ($CC) together with the first group ($FG) in the national significant number should be formatted when formatWithCarrierCode is called, if carrier codes are used for a certain country.
