=head1 NAME

Data::Sah::Coerce::perl::To_str::From_str::normalize_cryptoexchange_account - Normalize cryptoexchange account

=head1 VERSION

This document describes version 0.009 of Data::Sah::Coerce::perl::To_str::From_str::normalize_cryptoexchange_account (from Perl distribution Data-Sah-CoerceBundle-App-cryp), released on 2019-11-28.

=head1 SYNOPSIS

To use in a Sah schema:

 ["str",{"x.perl.coerce_rules"=>["From_str::normalize_cryptoexchange_account"]}]

=head1 DESCRIPTION

Cryptoexchange account is of the following format:

 cryptoexchange/account

where C<cryptoexchange> is the name/code/safename of cryptoexchange as listed in
L<CryptoExchange::Catalog>. This coercion rule normalizes cryptoexchange into
safename and will die if name/code/safename is not listed in the catalog module.

C<account> must also be [A-Za-z0-9_-]+ only and not exceed 64 characters in
length.
