Instance methods

==(other : self)

Returns true if this reference is the same as other. Invokes same?.

access_time

Source

access_time=(access_time : Time)

Source

change_time

Source

change_time=(change_time : Time)

Source

dev_major

Source

dev_major=(dev_major : Int64)

Source

dev_minor

Source

dev_minor=(dev_minor : Int64)

Source

file_info

file_info returns an File::Info for the header

Source

flag

Typeflag is the type of header entry. The zero value is automatically promoted to either REG or DIR depending on the presence of a trailing slash in Name.

Source

flag=(flag : UInt8)

Typeflag is the type of header entry. The zero value is automatically promoted to either REG or DIR depending on the presence of a trailing slash in Name.

flag=(v : Int)

format

Source

format=(format : Format)

gid

gid=(gid : Int32)

gid=(v : Int)

gname

gname=(gname : String)

Source

hash(hasher)

See Object#hash(hasher)

Source

link_name

Source

link_name=(link_name : String)

Source

mod_time

If the Format is unspecified, then Writer#write_header rounds mod_time to the nearest second and ignores the access_time and change_time fields.

To use access_time or change_time, specify the Format as PAX or GNU. To use sub-second resolution, specify the Format as PAX.

Source

mod_time=(mod_time : Time)

If the Format is unspecified, then Writer#write_header rounds mod_time to the nearest second and ignores the access_time and change_time fields.

To use access_time or change_time, specify the Format as PAX or GNU. To use sub-second resolution, specify the Format as PAX.

mode

mode=(mode : Int64)

name

name=(name : String)

pax_records

pax_records is a map of PAX extended header records.

User-defined records should have keys of the following form: VENDOR.keyword Where VENDOR is some namespace in all uppercase, and keyword may not contain the '=' character (e.g., "CRYSTAL.mod.version"). The key and value should be non-empty UTF-8 strings.

When Writer#write_header is called, PAX records derived from the other fields in Header take precedence over PAXRecords.

Source

pax_records=(pax_records : Hash(String, String))

pax_records is a map of PAX extended header records.

When Writer#write_header is called, PAX records derived from the other fields in Header take precedence over PAXRecords.

size

size=(size : Int64)

size=(v : Int)

uid

uid=(uid : Int32)

uid=(v : Int)

uname

uname=(uname : String)

Source

xattr

xattr stores extended attributes as PAX records under the "SCHILY.xattr." namespace.

The following are semantically equivalent: h.Xattrs[key] = value h.PAXRecords["SCHILY.xattr."+key] = value

When Writer#write_header is called, the contents of xattr will take precedence over those in PAXRecords.

Source

xattr=(xattr : Hash(String, String))

xattr stores extended attributes as PAX records under the "SCHILY.xattr." namespace.

The following are semantically equivalent: h.Xattrs[key] = value h.PAXRecords["SCHILY.xattr."+key] = value

When Writer#write_header is called, the contents of xattr will take precedence over those in PAXRecords.
